My father narrated to us. He said: Muhammad b. Abi'l Qasim narrated to us from Muhammad b. `Ali al-Kufi from Muhammad b. Sinan from al-Mufaddal b. `Umar from Abi `Abdillah al-Sadiq . He said:

Whoever reports something about a believer intending for him to be harmed and for his reputation to be destroyed so that he may fall in the eyes of the people, Allah will take him out of His wilaya and put him in the wilaya of Satan.
