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."
حَدَّثَنَا مُحَمَّدٍ، قَالَ: حَدَّثَنَا مُوسَى، قَالَ: حَدَّثَنَا وُهَيْبٌ، قَالَ: أَخْبَرَنَا دَاوُدُ، عَنْ عَامِرٍ قَالَ: حَدَّثَنِي أَبُو جَبِيرَةَ بْنُ الضَّحَّاكِ قَالَ: فِينَا نَزَلَتْ، فِي بَنِي سَلِمَةَ: {وَلاَ تَنَابَزُوا بِالأَلْقَابِ}، قَالَ: قَدِمَ عَلَيْنَا رَسُولُ اللهِ صلى الله عليه وسلم وَلَيْسَ مِنَّا رَجُلٌ إِلاَّ لَهُ اسْمَانِ، فَجَعَلَ النَّبِيُّ صلى الله عليه وسلم يَقُولُ: يَا فُلاَنُ، فَيَقُولُونَ: يَا رَسُولَ اللهِ، إِنَّهُ يَغْضَبُ مِنْهُ.
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!'"
Hukaym ibn Sa'd heard 'Ali say, "Do not be hasty, spreading and
divulging secrets. Ahead of you lies a severe, distressing affliction and
events which would take a long time explain - namely oppressive conflicts."
