Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "I give some people (wealth and the like), thereby winning their hearts, and I entrust other people to what (faith) they have (the narrator is unsure; perhaps the words are:) I entrust them to what (faith) Allah Almighty has placed in their hearts. Among them is Furat bin Hayyan."
Imam al-Bazzar recorded it. Its chain contains Dirar bin Surad, who is da'if (weak).
