"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.

"Indeed Allah and His angels bless the Prophet; O you who have faith! Invoke blessings on him and invoke Peace upon him in a worthy manner." Quran (33:56)

Prophet Muhammad (PBUH&HP) was the last messenger sent by Allah to guide human beings toward a more prosperous and meaningful life. His life was full of challenges and difficulties. However, he never gave up on his holy mission and strived to save as many souls as he could. His characteristics were unique and exemplary, which made him the best choice for prophethood, the beloved of Allah (Habibullah).   

Family background 

Prophet Muhammad (PBUH&HP) was the son of Abdullah and Amina, the grandchild of Abd al-Muṭṭalib and from the Banu Hashim clan. He was born in Mecca about the year 570 A.C, in the month of Rabi’ al-awwal [1]. Being taken care of by his paternal grandfather, Abd al-Muṭṭalib, and then by his uncle Abu-Talib, father of Ali (AS), who loved him a lot and regarded him dearer than his own children [2], he learned a little about the merchandise. He was well-known and called Al-Amin, meaning the trustee, due to his honesty and faithfulness [3]. This reputation attracted Khadijah, and she proposed him for marriage. He married this 40-year-old woman at the age of 25 [4]. This was a happy marriage, by all means. They lived a happy life, and they had many children, of which all the male ones passed away, and their most famous daughter is Fatimah (AS). Little is known about his youth before becoming a prophet. One fact is certain; he was absolutely against the discriminating behaviors and beliefs of the people of his era.

Prophet Muhammad (PBUH&HP)'s Social, Political and Personal Life 

Prophet Muhammad (PBUH&HP) was a kind and generous man. He was known for his modesty, honesty, and trustworthiness. He never disrespected anyone and cared a lot about his appearance in society; although his clothes were mostly ragged, they were neat and clean. His hygiene was another important fact in his life. Family, as the smallest unit of society, was the most important thing for him. He had a deep respect for his wife and her daughters, especially Fatimah [5].

His political life started with inviting the members of his family and clan to Islam, and then, publically announcing Islam as the true faith sent by Allah for human beings. Soon after the public announcement, many of the heads of clans began to rise against him, and he migrated to Medina, and there, he formed the first Islamic government. His strategy was friendship and peace, and the Quba mosque was the center of his government [6]. He never forced anyone to convert to Islam. Instead, he brought logical words and verses of the Quran and spoke gently with the people he wanted to invite. Even when he tried to ask people of the other religion to convert to Islam, he used their own words and verses from their holy books. All in all, he followed the steps Allah had taught him to guide human beings to the right path: 

“Invite to the way of your Lord with wisdom and proper instruction, and argue with them in the best way. Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of who is [rightly] guided." (16:125)

Harra Cave: Islam Comes to Life

It was a tradition among some Hashemi Arabs, Called Hunafa, to go to the Harra cave during the month of Ramadan and then come back after the end of the month. Actually, it was Prophet Muhammad’s (PBUH&HP) grandfather who made it up. Muhammad(PBUH&HP) was not an exception.

On the contrary, he was one of the fans of staying alone in that cave and worshiping Allah, his only God and the God of his fathers, up to prophet Abraham [7]. On one of those nights of Ramadan, Gabriel descended to him and asked him to read. Muhammad (PBUH&HP) said: “I can’t.” Gabriel repeated, and he again denied. Then Gabriel recited the first verses of the Quran sent by Allah: 

Recite in the name of your Lord who created -
Created man from a clinging substance. 
Recite, and your Lord is the Most Generous –
Who taught by the pen -
Taught man that which he knew not.  (96:1-5)

Muhammad’s (PBUH&HP) great mission had started. He found out that it was not a typical experience. He came back home and then returned to the cave. All of The Holy Quran descent to him in one of those holy nights: 
"Indeed, We sent the Qur'an down during the Night of Decree." (97:1)

The Quran; not His only Miracle

That Quran was descended to Prophet Muhammad (PBUH&HP) in one night and that he became able to read in a few minutes is not the only miracle of Prophet Muhammad (PBUH&HP).  He had other miracles like dividing the moon into two, reviving the dead, the testify of stones in the palm of his hand, etc. we are going to discuss these miracles in our next articles broadly [8]. 

The fact is that the events of that night of Ramadan made Muhammad (PBUH&HP) a prophet. Later on, people interacted with him, saw, felt, and understood his truthfulness, and stepped on the path of Islam. His lifestyle, social, political, and even family interactions carried badges of acceptance and appreciation that were imitated by the truth-seeking people. He was not the prophet belonging to centuries ago, but of all guided human beings.
