Zaid b. Aslam said that 'Umar b. al-Khattab drank some milk which pleased him and asked the one who had given him the drink where he had got that milk from. He informed him that he had gone down to a watering-place which he named where there were some of the camels of the sadaqa. The people who were watering the camels had drawn some milk for him which he had put in his milk-skin, and that was what he had given him. ‘Umar then put his hand in his mouth and vomited it.
Ibn 'Umar said that if anyone buys a garment for ten dirhams among which is one unlawfully acquired, God most high will not accept prayer from him as long as he wears it. He then put a finger in each ear and said, “May they become deaf if the Prophet was not the one I heard say it!”
Baihaqi transmitted it in Shu'ab al-iman, saying that its isnad is weak.
Abu Bakr had a slave who brought him his earnings and Abu Bakr would eat* some of his earnings. One day he brought him something and when Abu Bakr had eaten some of it the slave asked him whether he knew what it was. Abu Bakr asked what it was, and he replied, "I acted as a soothsayer for a man in the pre-Islamic period, and not being good at it, I deceived him; but he met me and gave me that, so this is the thing of which you have eaten.” She said that Abu Bakr then put his hand in his mouth and vomited everything which was in his stomach.
Bukhari transmitted it.
* Here the word is used in its literal sense. Elsewhere the word is often translated by "enjoy when it is not clear that something is actually eaten.”
