2. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn Sinan from ‘Imran al-Za’farani from Muhammad ibn Marwan who has said the following: “I heard abu Ja’far عليه السلام saying, ‘If one learns that there is a certain reward from Allah for a certain act and he performs such act to receive such reward, he will be given the reward even if, in fact, the Hadith may not be as such that has come to him.’”
