'Aishah, the wife of the Prophet (saws) told him that there were four types of marriage during Pre-Islamic period of Ignorance. One type was similar to that of the present day i.e. a man used to ask somebody else for the hand of a girl under his guardianship or for his daughter's hand, and give her Mahr and then marry her. The second type was that a man would say to his wife after she had become clean from her period. "Send for so-and-so and have sexual intercourse with him." Her husband would then keep away from her and would never sleep with her till she got pregnant from the other man with whom she was sleeping. When her pregnancy became evident, he husband would sleep with her if he wished. Her husband did so (i.e. let his wife sleep with some other man) so that he might have a child of noble breed. Such marriage was called as Al-Istibda'. Another type of marriage was that a group of less than ten men would assemble and enter upon a woman, and all of them would have sexual relation with her. If she became pregnant and delivered a child and some days had passed after delivery, she would sent for all of them and none of them would refuse to come, and when they all gathered before her, she would say to them, "You (all) know waht you have done, and now I have given birth to a child. So, it is your child so-and-so!" naming whoever she liked, and her child would follow him and he could not refuse to take him. The fourth type of marriage was that many people would enter upon a lady and she would never refuse anyone who came to her. Those were the prostitutes who used to fix flags at their doors as sign, and he who would wished, could have sexual intercourse with them. If anyone of them got pregnant and delivered a child, then all those men would be gathered for her and they would call the Qa'if (persons skilled in recognizing the likeness of a child to his father) to them and would let the child follow the man (whom they recognized as his father) and she would let him adhere to him and be called his son. The man would not refuse all that. But when Muhammad (saws) was sent with the Truth, he abolished all the types of marriages observed in pre-Islamic period of Ignorance except the type of marriage the people recognize today.

Allah's Apostle very often used to ask his companions, "Did anyone of you see a dream?" So dreams would be narrated to him by those whom Allah wished to tell. One morning the Prophet said, "Last night two persons came to me (in a dream) and woke me up and said to me, 'Proceed!' I set out with them and we came across a man lying down, and behold, another man was standing over his head, holding a big rock. Behold, he was throwing the rock at the man's head, injuring it. The rock rolled away and the thrower followed it and took it back. By the time he reached the man, his head returned to the normal state. The thrower then did the same as he had done before. I said to my two companions, 'Subhan Allah! Who are these two persons?' They said, 'Proceed!' So we proceeded and came to a man lying flat on his back and another man standing over his head with an iron hook, and behold, he would put the hook in one side of the man's mouth and tear off that side of his face to the back (of the neck) and similarly tear his nose from front to back and his eye from front to back. Then he turned to the other side of the man's face and did just as he had done with the other side. He hardly completed this side when the other side returned to its normal state. Then he returned to it to repeat what he had done before. I said to my two companions, 'Subhan Allah! Who are these two persons?' They said to me, 'Proceed!' So we proceeded and came across something like a Tannur (a kind of baking oven, a pit usually clay-lined for baking bread)." I think the Prophet said, "In that oven there was much noise and voices." The Prophet added, "We looked into it and found naked men and women, and behold, a flame of fire was reaching to them from underneath, and when it reached them, they cried loudly. I asked them, 'Who are these?' They said to me, 'Proceed!' And so we proceeded and came across a river." I think he said, ".... red like blood." The Prophet added, "And behold, in the river there was a man swimming, and on the bank there was a man who had collected many stones. Behold, while the other man was swimming, he went near him. The former opened his mouth and the latter (on the bank) threw a stone into his mouth whereupon he went swimming again. He returned and every time the performance was repeated. I asked my two companions, 'Who are these (two) persons?' They replied, 'Proceed! Proceed!' And we proceeded till we came to a ...

I did not offer behind anyone after the Messenger of Allah (saws) a prayer like the prayer offered by the Messenger of Allah (saws) than this youth, i.e. Umar ibn AbdulAziz. We estimated reciting glorification ten times in his bowing, and in his prostration ten times.

Abu Dawud said: Ahmad b. Salih said: I asked him ('Abd Allah) whether the name Manus is correct of Mabus. He replied: 'Abd al-Razzaq used to say Mabus, but I remember Manus (i.e. the narrator Wahb b. Manus). These are the words of Ibn Rafi'. It has also been narrated by Ahmad from Sa'id b. Jubair on the authority of Anas b. Malik.
