Jami` at-Tirmidhi Book 2, Hadith 238 Next Hadith → "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.'"
