Throughout the history of humankind, strong women have always been a source of inspiration and growth. Women who, alongside men, brought significant changes to the world, making it a better place to live and to prosper. One of the most prominent and praised women in the history of Islam is Lady Khadija (AS), Prophet Muhammad's (PBUH&HP) wife and companion, who had a vital role in the spread of Islam. She was one of those women whose influence and exceptional characteristics still resonates throughout the ages and among many generations after her. 

In what follows, we will look at the life of Lady Khadija (AS), this distinguished personality. 

Birth and Lineage

Known as Khadīja al-Kubrā (AS) and Umm al-Mu' minīn (the Mother of Believers), Lady Khadija (AS) was born fifteen years before Am Al-Fil [i]. Therefore, her birth date is approximately 555 A.D. Her father, a famous figure in the Quraysh tribe in Mecca, was Khuwaylid b. Asad b. Abd al-Uzza b. Qusayy [1] and her mother was Fatima bt. Za'ida [2]. According to some sources, Lady Khadija (AS) had a distant relation in lineage with Prophet Muhammad (PBUH&HP), and their roots went back to the same ancestors [3]. 

Lady Khadija (AS)'s Reputation before Marrying Prophet Muhammad (PBUH&HP)

The available information concerning Lady Khadija (AS) before marrying Prophet Muhammad (PBUH&HP) is limited and scarce. Nevertheless, she was known to be a wealthy merchant who employed others to work for her and benefited from a part of the profit [4]. Due to her ancestral nobility, she was of high social status and respected among her people. As Ibn Sayyid al-Nas said: "She was an honorable and wise lady, and God granted her with His blessing." [5]

Meeting Prophet Muhammad (PBUH&HP)

According to some sources, before meeting Prophet Muhammad (PBUH&HP) in person and starting a business relation with him, Lady Khadija (AS) had heard about his trustworthiness and honesty. Therefore, she asked Muhammad (PBUH&HP) to join her and help her in expanding her business [6].

Prophet Muhammad (PBUH&HP) went at least five business trips for Lady Khadija (AS), the most important of which that led to their marriage was the business trip to Sham. Prophet Muhammad (PBUH&HP) went back from this trip with the good news of their financial success and profit, which impressed Lady Khadija (AS) and made her decide to choose him as the head of one of the greatest caravans traveling to Sham. The result of these trips and Prophet Muhammad's (PBUH&HP) impressive actions, was Lady Khadija's (AS) fondness toward this honest man [7]. After that, she proposed marriage to Prophet Muhammad (PBUH&HP) [8].

Marriage to Prophet Muhammad (PBUH&HP)

Despite the disputes over Lady Khadija's (AS) marriage before Prophet Muhammad (PBUH&HP), which claim her to be a widow, many authentic sources believe that Lady Khadija (AS) did not marry anyone before the Prophet (PBUH&HP) and it was her first marriage [9]. This is also proved by looking at the cultural and intellectual status of Lady Khadija (AS) in Hijaz, which made it improbable for her to marry anyone from lower-status tribes [10]. 

While receiving many proposals for marriage from the heads of Quraysh, offering her vast amounts of money and wealth, she refused all and instead fell in love with the honesty and righteousness of Prophet Muhammad (PBUH&HP). The news of this proposal shocked Lady Khadija's (AS) family and relatives, who couldn't believe her to be willing to marry a man with lower financial status and younger than herself [11]. 

The proposal and marriage ceremony of these two significant figures, who made an example of their marriage to the generations that followed them, was held two months after the business trip to Sham, which was mentioned above [12]. According to many sources, at the time of their marriage, Prophet Muhammad (PBUH&HP) was twenty-five, and Lady Khadija (AS), forty years old [13]. After their marriage, she dedicated all her wealth to her husband and left the management of her business to him. Lady Khadija (AS) was the first wife of the Prophet Muhammad (PBUH&HP), and during her life, he did not marry another woman. 

Lady Khadija (AS)'s Children

There seems to be disagreement in the number of Lady Khadija (AS) and Prophet Muhammad's (PBUH&HP) children. The number ranges from six to eight, among which they include two sons and four daughters [14]. Some historians believe that Lady Fatima (AS) was the only daughter of the Prophet Muhammad (PBUH&HP) and Khadija (AS) and the other daughters were their adopted children [15]. 

Embracing Islam

After receiving the call to prophethood in the Hira cave, Prophet Muhammad (PBUH&HP) first told Khadija (AS) and Imam Ali (AS) about his prophetic mission. She totally trusted her husband to be an honest man and believed in his great cause; therefore, she was the first woman who accepted Prophet Muhammad's (PBUH&HP) invitation to Islam and became a devout Muslim. Imam Ali (AS) and Lady Khadija (AS) were also the first ones who performed prayer (Salat) alongside Prophet Muhammad (PBUH&HP) in the mosque [16]. 

Sacrifices for Islam and Muslims

As a wife, Lady Khadija (AS) always supported Prophet Muhammad (PBUH&HP) in fulfilling his extraordinarily challenging and demanding mission of guiding people toward the path of Allah. At the times when people hurt the Prophet (PBUH&HP) with their offenses and unfair accusations, Khadija (AS) was there to soothe him, wipe his sadness away and give him hope to endure the hardships of this holy mission. She also financially supported Prophet Muhammad (PBUH&HP) when they were suffering from unfair economic sanctions in the Shaib al-Abi Talib [17]. Prophet Muhammad (PBUH&HP) always appreciated Lady Khadija's (AS) unbounded help and support and said: "No money was profitable for me the way the wealth of Khadija (a) was." [18]

Notable Characteristics 

One of The Best Women of all Times

Prophet Muhammad (PBUH&HP) always loved and praised Lady Khadija (AS) for her great and exemplary personality. He used to consider her among the four praised women of all time, including Asiya [ii], Mary, and Lady Fatima (AS) [19]. She was not only a prominent and influential figure of her own time but also set an example for the generations that followed her. Her power in merchandise and business at one point, her courage, and insight in choosing a perfect husband by herself and her devotion to her married life at another, made her an ideal role model for the women all around the world.

The Wise Lady

As it was mentioned above, Lady Khadija (AS) was a well-known woman before her marriage to Prophet Muhammad (PBUH&HP). She was famous for her knowledge and sagacity, which manifested in her thriving business, whose fame reached all over the Hijaz. Despite the patriarchal society of her time, she had managed to establish herself as a powerful businesswoman who won the respect of great heads of the tribes and men who considered women inferior to themselves [20].   

The Modest Lady 

While having an active and productive role in society, Lady Khadija (AS) always preserved her modesty and presented a modest manner in her interactions with men. Doing so, rather than being praised for her physical beauty, she was honored and respected for her insight and chastity, which encouraged many of the powerful men of her time to ask her hand in marriage. Yet, since she was more interested in finding an honest and virtuous man to marry, rather than a merely wealthy man, she refused all her suitors. Finally, she found these features in Prophet Muhammad (PBUH&HP) and chose him as her perfect match. 

The Devout and Beloved Companion

When she made a vow of marriage to the honest Muhammad (PBUH&HP), she knew that her life with this man would be different. When Prophet Muhammad's (PBUH&HP) mission began, she realized how much he was under pressure and needed her companionship and support. People didn't believe in him, didn't listen to him, and refused to be guided through the words of Allah, especially in the first years of his invitation to Islam. Yet, at home, he had someone who was always by his side, wipe his sadness away, and had faith in his call.  Prophet Muhammad (PBUH&HP) never loved any woman as Lady Khadija (AS), and never forgot about her love and sacrifices, always remembering her as a unique and precious person in his life [21]. 

Lady Khadija (AS)'s Demise

Lady Khadija (AS), this honorable woman, passed away in the month of Ramadan ten years after Prophet Muhammad's (PBUH&HP) call to prophethood in 619 A.D. She was 65 years old at the time of her demise [22], [23]. She was buried by Prophet Muhammad (PBUH&HP) in al-Ma'lat Cemetery, on the slopes of Mount Al-Hajun in Mecca. This sorrow was shortly followed by the demise of Abu-Talib, Prophet Muhammad's (PBUH&HP) uncle. These tragic incidents afflicted Prophet Muhammad (PBUH&HP) with deep grief to the extent that he named that year as "the year of sorrow and pain (Am al-Huzn) [24].

Notes:

[i] Literally meaning the year of the Elephant, it is the year in which Abraha, the king of Yemen, started a huge military expedition toward Mecca to destroy Ka'ba. As he had an army with war elephants, the year turned to be known as the year of the Elephant.
[ii] Pharaoh's wife at the time of Prophet Moses (PBUH)

"Although most modern dogs are kept as pets, there are still a tremendous number of ways in which dogs can and do assist humans, and more uses are found for them every year" [1]. This animal is used in many activities such as rescuing, herding, sledding, hunting, guarding, tracking, and Human Remains Detection.There are also war and police dogs, which all indicate the versatility of this animal. But in Islam, there are some restrictions regarding the relationship with this useful creature.The term "impure" (Najis) in Islamic jurisprudence refers to things that are avoided because of the intensity of filth in them, one of which is dogs. The religion of Islam has warned Muslims to keep dogs “as pets” since they are deemed dirty. Now, let’s see why:

The Impurity of Dogs

Unless properly trained, dogs will defecate and urinate where ever they please; they also slobber everywhere, which doctors say is the cause of many diseases and infections.

Even though the level of awareness about the hazards of having a dog has increased among dog owners and necessary precautions about keeping it as a pet have been taken by them, dog bites continue to be a public health problem in the USA [1].

Doctors always warn about diseases we may catch from dogs: “Hookworms and roundworms (Ancylostoma and Ascaris) are common nematodes of dogs. When a human accidentally eats something contaminated with worm eggs from a pet’s stool, the eggs hatch in the intestines and begin migrating throughout that person’s body” [2].

From the viewpoint of Islam, when we speak about the impurity of the dog, we mean its "outward" filth and all its organs including skin, flesh, and hair. So, everything is considered as "impure" in contact with a wet dog or vice versa (a wet thing in contact with a dog). Almost all Muslim scholars do not doubt that dogs are impure animals. There are many narrations (Hadiths) about the impurity of dogs in authentic narration books, including:

“Allah has not created a creature more impure than dogs” [3].
“If your clothes get dampened by a dog, then you must wash them” [4].

The Fidelity of Dogs

Perhaps, one of the reasons for Islam to prohibit Muslims from keeping dogs as pets [3] is due to the high fidelity of these animals. The bond between dogs and their owners has an important impact on family relationships in a way that the dog owner may forget his family members and relatives, adore his/her pet, and neglect God’s worship as well.

It has been reported that “More and more US women are forgoing motherhood and getting their maternal kicks by owning handbag-size canines” [5].

Trained dogs in Islam

There are possibly two reasons for a person to have a dog: affection for the animal or security.

In the first case, the dog will most probably live with you in your house, which is prohibited according to Islamic law.

And in the second one, the case of security, the dog is mostly kept on the periphery of your house or property; like the dogs that are held for hunting, guarding livestock, crops, and for guarding houses, etc. These dogs are called trained dogs (Kalb-e-Moallam) in Islam and the rules regarding them are different from the ones for the other kinds of dogs.

There are exceptions to them, and they are not considered “impure” because of their skills. This fact has been mentioned in the Holy Quran directly: “As for what you have taught hunting dogs [to catch], teaching them out of what Allah has taught you, eat of what they catch for you and mention Allah’s Name over it …” (5:4)

Do Muslims hate dogs?

But do Muslims consider dogs as filthy and useless creatures? No. because these animals are also creatures of God. Similarly, despite its many benefits and its importance for human life, human blood is also regarded as impure in Islamic teachings.

In other words, dogs’ impurity does not deny the existence of their good features such as loyalty or innocence, just as the impurity of human urine, feces, and blood has nothing to do with his/her humanity.

On the other hand, Islam has proposed very detailed rights for all kinds of animals including dogs, which a Muslim must respect and observe. For example, one day when Imam Hussain (AS) saw his servant sharing his food with Imam’s garden guard dog, he highly admired the servant for his kind behavior, rewarded him with 1000 Dinars and even donated the garden to him just for observing the right of a dog [6].

Is that all?

The words mentioned above reveal the Islamic view of dogs. But is that all? Have we successfully and thoroughly looked into it to reach firm ideas about dogs?

To tell you the truth, we are not always able to understand the essence of Islamic rules and guidelines. More importantly, Muslims have learned to fully observe the practices ordained by God because they believe these practices are best for them, just like following the instructions that come with the electronic devices without questioning them.

If God, the Prophet (PBUH&HP), and infallible Imams (AS) prohibit specific practices, it is definitely because they have certain harmful effects on us that may or may not be immediate or measurable.

“…while He has already elaborated for you whatever He has forbidden you, excepting what you may be compelled to [eat in an emergency]? Indeed many mislead [others] by their fancies, without any knowledge. Indeed your Lord knows best the transgressors.” (6:119)

In a nutshell

It is permissible to keep dogs for security purposes in Islam, but you cannot let them inside your house. However, this does not mean we can harm dogs or hate them, Not at all; on the contrary, we should always be compassionate with dogs as much as we should be with any other living kind.
