Hadith 87
´Madan bin Abi Talhah narrated from Abu Ad-Darda that :` "Allah's Messenger vomited [so he broke fast] so he performed Wudu." So I met Thawban in a Masjid in Damascus, and I mentioned that to him. He said: 'He told the truth, I poured the water for his Wudu."
Hadith 388
´Ma'dan bin Talhah Al Yamari said:` "I met Thawban the freed slave of Allah's Messenger (S) and said to him, 'Guide me to a deed by which Allah benefit me, and for which Allah will admit me into Paradise.' He was silent for quite a while, then he turned to me and said: 'Perform prostrations, for I heard Allah's Messenger (S) saying: 'No worshipper performs a prostration to Allah except that by it, Allah will raise him a level, and erase a sin from him for it.'"
