His birth was on the twelfth (12) of Rabiul Awwal 53 B.H. (570 A.D of the Christian era) was ordinary and has no significance in Islam and the celebrations on this occasion have nothing to do with shari’ah and some people consider it Bid’ah.
Abdul Mutalib, his grandfather who was the chief of Makkah at that time, showed pride in him as Muhammad (s.a.w.s.) compensated him for the loss of his son who died in the prime of his youth. His mother showed affection for her son as she awaited the best nurses to come and take care of him: The tradition at that time was that nurses would come from the desert seeking to be the custodians of the children of nobility in return for good pay and gifts. Giving that Muhammad (s.a.w.s.) was not wealthy all nurses turned away from him, Halimah of the Banu Saad tribe was one of them, but when she could not find any other child she was ashamed to return home empty handed, so she went back and took Muhammad (s.a.w.s.), and since then Allah showered his mercy on her; for instance animals started giving plenty of milk after they had been dried. Therefore, her and her husband felt they were blessed to have taken Muhammad (s.a.w.s.) and became very attached to him.
Muhammad (s.a.w.s.) spent five years with Banu Saad during which nothing out of the ordinary happened except one told incident which scared Halimah and became known as “the splitting of his chest.” When he was playing with the other boys Jibril held him, threw him down, split his chest, took out his heart and took out a clump from it and said: “this is Satan’s portion of you.” Then he washed him in a basin made of gold with the water of zamzam, then sealed his chest and returned him where he was. The boys ran to Halimah and said Muhammad (s.a.w.s.) has been killed. They came back and found him alive but pale. (Reported by Anas in the Hadith compilations of Muslim and Ahmed)
Muhammad (s.a.w.s.) returned to Makkah at the age of five to his mother and grandfather who took good care of him, but the days refused to allow him tranquility among those tender hearts, as his mother died during a visit to Madinah to visit her husbands grave. She took Muhammad (s.a.w.s.) and his maid Umm Aiman with her. On the way back, she fell very sick and died in Abwaa leaving Muhammad (s.a.w.s.) with Umm Aiman.
His grandfather always took good care of him and never left him alone, he took him to all public gatherings. However, at the age of eight, Abdul Muttalib died leaving him into his uncle Abu Talib’s care. Since Abu Talib had many children and was not wealthy, Muhammad (s.a.w.s.) insisted on sharing the burdens of life with him. He went with his uncle on a trading journey to Syria at the age of thirteen. He met a monk called Bahira during the journey, who looked at his face and the sign on his back (the sign of Prophethood) and asked Abu Talib: “What is this boy to you ?”My son he said.” “His father should not be alive.” Said Buhira. Abu Talib then said, “Yes, in fact he is my brother’s son “and told him the rest of the story. The monk said “Now you are telling me the truth. Take him back and be careful of the Jews over him.”
Muhammad (s.a.w.s.) then returned to Makkah and resumed his life, working as a shepherd in his early life. He did not acquire knowledge or education from a monk or a philosopher or sorcerer, as was the norm then. Instead he read through the pages of life and took what he found good. He combined the good qualities of discipline with spiritual purity, rightness and contentment.
In this manner, he entered his third phase of life and got acquainted with his first wife Khadija (r.a.) who was a merchant woman of nobility and wealth. She had heard of his truthfulness and trustworthiness, so she offered him to take her trade to Syria (before marrying him). He was 25 years old and she was 40 years old when they got married. Their marriage lasted until she died at the age of 65.
