Abdur Rahman bin Auf was born around 580 C.E., and was younger than the Holy Prophet by ten years. He was one of the early converts to Islam. He was related to Uthman and was married to a step sister of Uthman. In the battle of Uhud he received twenty-one wounds while defending the Holy Prophet. On this occasion he also lost some of his teeth. He was a trader and a shrewd businessman. It is related that when he came to Madinah his Ansar brother Sa 'ad proposed to give half of his property to him. Sa'ad had two wives, and he proposed to divorce one of them so that Abdur Rahman could marry her. Abdur Rahman thanked his brother and said that he did not need his property or any of his wives. He merely wanted him to show him the way to the market, and he would make his own fortune. Soon Abdur Rahman was able to build a great fortune. He amassed considerable wealth and came to be regarded as one of the richest men in Madina.
