Sahih al-Bukhari 7302
Narrated Ibn Abi Mulaika:
Once the two righteous men, i.e., Abu Bakr and `Umar were on the verge of destruction (and that was 
because): When the delegate of Bani Tamim came to the Prophet, one of them (either Abu Bakr or 
`Umar) recommended Al-Aqra' bin H`Abis at-Tamimi Al-Hanzali, the brother of Bani Majashi (to be 
appointed as their chief), while the other recommended somebody else. Abu Bakr said to `Umar, "You 
intended only to oppose me." `Umar said, "I did not intend to oppose you!" Then their voices grew 
louder in front of the Prophet (ﷺ) whereupon there was revealed: 'O you who believe! Do not raise your 
voices above the voice of the Prophet..a great reward.' (49.2-3) Ibn Az-Zubair said, 'Thence forward 
when `Umar talked to the Prophet, he would talk like one who whispered a secret and would even fail 
to make the Prophet (ﷺ) hear him, in which case the Prophet (ﷺ) would ask him (to repeat his words).
حَدَّثَنَا مُحَمَّدُ بْنُ مُقَاتِلٍ، أَخْبَرَنَا وَكِيعٌ، عَنْ نَافِعِ بْنِ عُمَرَ، عَنِ ابْنِ أَبِي مُلَيْكَةَ، قَالَ كَادَ الْخَيِّرَانِ أَنْ يَهْلِكَا أَبُو بَكْرٍ، وَعُمَرُ، لَمَّا قَدِمَ عَلَى النَّبِيِّ صلى الله عليه وسلم وَفْدُ بَنِي تَمِيمٍ، أَشَارَ أَحَدُهُمَا بِالأَقْرَعِ بْنِ حَابِسٍ الْحَنْظَلِيِّ أَخِي بَنِي مُجَاشِعٍ، وَأَشَارَ الآخَرُ بِغَيْرِهِ، فَقَالَ أَبُو بَكْرٍ لِعُمَرَ إِنَّمَا أَرَدْتَ خِلاَفِي‏.‏ فَقَالَ عُمَرُ مَا أَرَدْتُ خِلاَفَكَ‏.‏ فَارْتَفَعَتْ أَصْوَاتُهُمَا عِنْدَ النَّبِيِّ صلى الله عليه وسلم فَنَزَلَتْ ‏{‏يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَرْفَعُوا أَصْوَاتَكُمْ‏}‏ إِلَى قَوْلِهِ ‏{‏عَظِيمٌ‏}‏‏.‏ قَالَ ابْنُ أَبِي مُلَيْكَةَ قَالَ ابْنُ الزُّبَيْرِ فَكَانَ عُمَرُ بَعْدُ ـ وَلَمْ يَذْكُرْ ذَلِكَ عَنْ أَبِيهِ يَعْنِي أَبَا بَكْرٍ ـ إِذَا حَدَّثَ النَّبِيَّ صلى الله عليه وسلم بِحَدِيثٍ حَدَّثَهُ كَأَخِي السِّرَارِ، لَمْ يُسْمِعْهُ حَتَّى يَسْتَفْهِمَهُ‏.‏
