Before she was born, both Prophet Muhammad (PBUH&HP) and lady Khadija (AS) went to a spiritual retreat separately for forty days by the command of Allah.  During those days, Prophet Muhammad (PBUH&HP) and Lady Khadija (AS) prayed Allah sincerely and prepared their pure soul to receive Allah's blessing, their beloved daughter. After those forty days of worship and servitude, angels brought Prophet Muhammad (PBUH&HP) an apple from heaven, and he broke his fast with those gifts from Allah. That night Lady Fatima (AS) was formed [1].

The father-daughter relationship between Prophet Muhammad (PBUH&HP) and Lady Fatima (AS) was one of a kind. Here, we are going to exemplify some instances of deep father-daughter love between the two and the formation of an ideal respectful relationship. 

1. Respecting and Loving Lady Fatima (AS) 

Prophet Muhammad (PBUH&HP) was always affectionate and caring toward Lady Fatima (AS). He used to kiss her throat every time she returned from a trip [2]. In response, she used to hug her dear father and kiss his forehead, between his eyes [3]. He didn't get to sleep before kissing her cheeks and praying for her, which reveal his deep respect and fatherly love toward her [4].  Aisha said she was the most similar person to Muhammad (PBUH&HP) in her speech. Whenever she came to see Prophet Muhammad (PBUH&HP), he used to take her hand and kiss her and sat next to her, and whenever Prophet Muhammad (PBUH&HP) went to meet Fatima (AS), she used to kiss his hand and sat next to him respectfully [5].

2. Lady Fatima (AS), The Mother of Her Father (Umme Abiha) 

Lady Fatima (AS) lost her mother when she was five. The other five years of her life passed without a mother. As a daughter, she used to take care of her father. Whenever the unbelievers threw him stones and ashes, Fatima (AS) used to take care of him and do what a mother does for her child. That is why when Allah asked Prophet Muhammad (PBUH&HP) to call his wives Umol-Mumenin (Mother of the Believers), she asked him to grant her a title, too, Then Prophet Muhammad (PBUH&HP) called her Umme Abiha, the mother of her father [6]. 

3.The Event of the Cloak

Prophet Muhammad (PBUH&HP) was at home, resting, with his cloak over his body. Fatima (AS) came beside him with some food. Prophet Muhammad (PBUH&HP) asked her to call her husband, Ali (AS), and her two sons, Hassan (AS) and Hussain (AS). They started eating together when Allah inspired this verse to his Prophet: 

"Stay in your houses and do not flaunt your finery like the former [days of pagan] ignorance. Maintain the prayer and pay the zakat, and obey Allah and His Apostle. Indeed, Allah desires to repel all impurity from you, O People of the Household, and purify you with a thorough purification." Quran (33:33)

Then Prophet Muhammad (PBUH&HP) covered the four of them with the remaining of his cloak and prayed:

O Allah, these are the people of my household and my special ones. Keep them pure and clean and take all evil away from them [7]. 

4. Attached, Even in the Other World

Prophet Muhammad (PBUH&HP) used to know about the difficulty of Lady Fatima's (AS) life after his death and the cruelty imposed on her and her family, and he cried for that a lot. Once when she was crying, he inspired her with this news: "You will join me in the other world soon after" [8] Lady Fatima (AS) was martyred 95 days after the death of his father!

We keep hearing arguments about Islam from different people. Some question Islam as a real religion, and others try to prove that Islam is the true religion sent by God. However, I think that there is a major problem with these types of arguments. In fact, many people who undermine Islam by questioning it are not usually in search of truth. Rather, their sole goal is to humiliate Islam and make themselves happy with whatever belief they have. 

Although Islam encourages people not to accept anything without understanding, when it comes to the point where arguments and discussions have no learning point, and become only a waste of time, Islam orders Muslims not to argue with people who have no intention to learn and improve; “do not dispute concerning them, except for a seeming dispute”. (18: 22)

Therefore, in this text, I would not try to justify the validity of Islam for those who have no intention to consider Islam as a path in life. But I would like to share my amazing experiences of being a Muslim with those who are looking for a safe path in life. Also, I will explain why I believe that Islam is the most complete religion and guideline in the world. 

All Prophets were Muslims

Is that true to say all prophets from Adam, Abraham, Moses, Jesus to Prophet Muhammad (peace be upon them) were Muslims? Or is it just a tool that Muslims use to justify Islam as the best religion? To find the answer to this question, we must first understand what Islam is.  

The word Islam means submission, and Muslim is the person who is submitted to God and His divine orders. Now, let’s have a look at the following verses of the Quran that state all religions that have been sent by God were sent to make humankind submitted to God (Muslims).

Abraham (PBUH) as a Muslim

In Chapter Baqarah when the story of Abraham and his son Ishmael (PBUT) is narrated, while they are making the house of God in the current city of Makkah, they pray God to make them Submissive (Muslim) to Him: 

“As Abraham raised the foundations of the House with Ishmael, [they prayed]: ‘Our Lord, accept it from us! …. ‘Our Lord, make us submissive to You, and [raise] from our progeny a nation submissive to You …” (2: 127-8) And then in another chapter of the Quran, Allah informs believers that Islam first came from Abraham; “The faith of your father, Abraham. He named you ‘Muslims’.” (22: 78)

Also God orders the Prophet Muhammad (PBUH) to emphasize the fact that the religion he brought is the same as the religion of Abraham (PBUH): “(O Prophet!) Say, ‘Indeed my Lord has guided me to a straight path, the upright religion, the creed of Abraham, a Hanif, and he was not one of the polytheists.” (6: 161)

Moses, Josef (PBUH) and Other Prophets as Muslims 

Prophet Josef (Yusuf) (PBUH) prays to his lord to take his soul while he is a Muslim: “Let my death be in submission [to You], and unite me with the Righteous.” (12: 101)

“And Moses said, ‘O my people! If you have faith in Allah, put your trust in Him, if you have submitted [to Him].’” (10: 84) The last part of this verse in the Quran is written as “if you are Muslims.” 

“Say, ‘We have faith in Allah and in what has been sent down to us, and what was sent down to Abraham, Ishmael, Isaac, Jacob, and the Tribes, and that which Moses, Jesus, and the prophets were given by their Lord. We make no distinction between any of them, and to Him do we submit.” (3:84)

Every Religion Is Islam

According to what we discussed so far, we release that “all Prophets irrespective of the fact whether they had or did not have an independent code of law, had the same mission and preached the same message.” [1] The prophets came with the same message from God to guide human beings to the right path, and the nature of human beings in all eras are the same; “So set your heart as a person of pure faith on this religion, the original nature endowed by Allah according to which He originated mankind (There is no altering Allah’s creation; that is the upright religion, but most people do not know.)” (30: 30) 

And in another verse, it is explained that:  “Indeed, with Allah religion is Islam, and those who were given the Book did not differ except after knowledge had come to them, out of envy among themselves...” (3:19)

Therefore, the guideline that is sent for human in all eras should be the same, as the nature of human beings in all periods has been the same. There are some rulings in the Quran that may change according to the conditions of the time. Since, Islam is a universal religion, not a contextual one. 

“Should anyone follow a religion other than Islam, it shall never be accepted from him, and he will be among the losers in the Hereafter.” (3: 85)

Why Islam of Muhammad (PBUH&HP)?

Now that we discussed all the prophets were Muslims, and the only religion sent by God was Islam, why do we say that the religion of Prophet Muhammad (PBUH) should be followed, not the religion of Prophet Moses (PBUH) or Prophet Jesus (PBUH) or even prophet Abraham who was the father of Muslims?

It is said in the Quran that Prophet Muhammad (PBUH&HP) was a role model for humankind: “There is certainly a good exemplar for you in the Apostle of Allah—for those who look forward to Allah and the Last Day.” (33:21) 

While it is also stated in the Quran that Prophet Abraham and his followers such as Prophet Lout (PBUT) were role models for mankind: “There is certainly a good exemplar for you in Abraham and those who were with him, when they said to their own people, ‘Indeed we repudiate you and whatever you worship besides Allah.” (60: 4)

As mentioned before, Islam started with Prophet Abraham (PBUH), and he is named in the Quran as the father of Muslims. While in the above verse he is mentioned as a role model for Muslims. The same is with Prophet Muhammad (PBUH) who is called a role model for Muslims. Therefore, one can conclude that the only thing that makes the religion of Prophet Muhammad (PBUH) the last and most complete religion is the growth of this religion throughout the time. 

People’s intellectual immaturity was the main reason why God renewed his message and developed it over time. However, by the advent of Islam and revelation of the holy Quran, humanity had passed the period of its childhood and had become mature enough to preserve its intellectual heritage, i.e., the religion of God [2].

Scientific Signs in the Quran

There are many scientific points in the Quran that has been mentioned about 1400 years ago. These issues have been discovered by scientists only during the past 200 years.  I would mention a few examples and will leave the rest for you to study in the Quran. 

Embryology 

Issues regarding embryology have been mentioned in the Quran: “Certainly We created man from an extract of clay. Then We made him a drop of [seminal] fluid [lodged] in a secure abode. Then We created the drop of fluid as a clinging mass. Then We created the clinging mass as a fleshy tissue. Then We created the fleshy tissue as bones. Then We clothed the bones with flesh. Then We produced him as [yet] another creature.” (23: 14) and in another chapter, it is said: “created man from a clinging mass.” (96: 2)

Cosmology 

With regards to Big bang as the start of this universe, Allah says: “Have the faithless not regarded that the heavens and the earth were interwoven and We unraveled them, and We made every living thing out of water?” (21: 30)

Many years ago people believed that the shape of the earth was flat and they had a fear of falling down the edge of the earth at a point when the earth is finished! [3] While 1400 years ago in the Quran Allah says: “It is He who created the night and the day, the sun and the moon, each swimming in an orbit.” (21: 33) “Thereafter He spread out the earth” (79: 30), but He mentions that although the earth is not flat, we have created in a way that you can walk on it without the fear of falling down: “Allah has made the earth a vast expanse for you.” (71: 19)

Anthropology: Quranic Verses that Are against Human Rights 

One of the reasons that some people stand strongly against Islam is that they say there are some rules in the Quran that are against human rights. In answer to such arguments, one should ask ‘Who defines human rights?’

Human rights that we have in our era is created by human beings and does not go any higher than human understanding. When a human mind tries to create human rights, with the best considerations, they may always forget about some other aspects of human being and the atmosphere around him. Therefore there is no doubt that in many cases, human rights that are written by human beings may be against real human rights. 

Quranic verses that do not make sense

Having discussed all the above points, I sometimes come to a point where I cannot understand some points of the Holy Quran according to my logic. What to do at these times?
I assume that a sound mind would say that when most of something makes complete sense to you and amazes you for its incredibility, then for that one percent, maybe I should think that the problem is not with the book, but with my understanding. 

In the end, I would like to invite people to wisely think about their way of life, their goals, and aims in life. I would like to ask every human to read the Quran as a book that would definitely have many pints for human growth in it; shall it be scientific, moral, social or lifestyle points, it can help all of us to experience a better personal and social life.
