Ibn 'Abbas said, "When you want to mention your companion's faults, remember your own faults."

Ibn 'Abbas spoke about the words of Allah Almighty, "Do not find fault with one another" (49

11) and he said that these words mean, "Do not attack one another."

Ad-Dahhak said, "It was about us (the Banu Salima) that these words were revealed, 'Do not find fault with one another' (49

11)" He went on to say, "The Messenger of Allah, may Allah bless him and grant him peace, came to us and there was not a man among us who did not have two names. The Prophet, may Allah bless him and grant him peace, began to say, 'O so-and-so!' and they said, 'Messenger of Allah! That will make him angry!'"

'Ikrima was heard to say, "I do not know which o f them, either Ibn 'Abbas or Ibn 'Umar, was giving his companions food, and a slavegirl was working in their presence. One of them said to her, 'Harlot!' He said, 'Easy! If she does not exact the hadd punishment (i.e. for slander) from you in this world, she will take it from you in the Next World.' The man said, 'And what do you think if it (what I said) is the truth?' He replied, 'Allah does not love anyone who greatly exceeds the sounds in speaking of indecencies."

'Abdullah reported that the Prophet, may Allah bless him and grant him peace, said. "The believer is neither a defamer nor a curser nor outrageous nor obscene."
