The servant (whose fault) Allah conceals in this world, Allah would also conceal (his faults) on the Day of Resurrection.
Sahih Muslim Book 45, Hadith 92
← Previous Hadith Do you know what is backbiting? They (the Companions) said: Allah and His Messenger know best. Thereupon he (the Holy Prophet) said: Backbiting implies your talking about your brother in a manner which he does not like. It was said to him: What is your opinion about this that if I actually find (that failing) in my brother which I made a mention of? He said: If (that failing) is actually found (in him) what you assert, you in fact backbited him, and if that is not in him it is a slander.
