Mishkat al-Masabih #842

Ma'dan b. Talha said: I met Thauban the client of God’s Messenger and asked him to tell me something I should do for which God would bring me into paradise. He gave no reply, so I asked him again, and when he still gave no reply I asked him a third time. He then said that he had asked God’s Messenger about that and received the reply, “Make frequent prostration before God, for you will not make one prostration without God raising you a degree because of it and removing a sin from you because of it.” Ma'dan said that he met Abud Darda’ later, and that when he asked him he received a reply similar to that given by Thauban. Muslim transmitted it.
