Narrated 'Abdullah bin Az-Zubair:

"Al-Aqra' bin Habis arrived to meet the Prophet ﷺ" - he said - "so Abu Bakr said: 'O Messenger of Allah! Appoint him over his people.' 'Umar said: 'Do not appoint him O Messenger of Allah!' They continued talking before the Prophet ﷺ until they raised their voices. Abu Bakr said to 'Umar: 'You only wanted to contradict me.' So ['Umar] said: 'I did not want to contradict you.'" He said: "So this Ayah was revealed: 'O you who believe! Do not raise your voices above the voice of the Prophet (49:2).'" He said: "After that, when 'Umar spoke before the Prophet ﷺ, his speech could not be heard until he told him he could not understand him." He (one of the narrators) said: "And Ibn Az-Zubair did not mention his grandfather" meaning Abu Bakr.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا مُؤَمِّلُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا نَافِعُ بْنُ عُمَرَ بْنِ جَمِيلٍ الْجُمَحِيُّ، حَدَّثَنِي ابْنُ أَبِي مُلَيْكَةَ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ الزُّبَيْرِ، أَنَّ الأَقْرَعَ بْنَ حَابِسٍ، قَدِمَ عَلَى النَّبِيِّ ﷺ فَقَالَ أَبُو بَكْرٍ يَا رَسُولَ اللَّهِ اسْتَعْمِلْهُ عَلَى قَوْمِهِ . فَقَالَ عُمَرُ لاَ تَسْتَعْمِلْهُ يَا رَسُولَ اللَّهِ . فَتَكَلَّمَا عِنْدَ النَّبِيِّ ﷺ حَتَّى ارْتَفَعَتْ أَصْوَاتُهُمَا فَقَالَ أَبُو بَكْرٍ لِعُمَرَ مَا أَرَدْتَ إِلاَّ خِلاَفِي . فَقَالَ عُمَرُ مَا أَرَدْتُ خِلاَفَكَ قَالَ فَنَزَلَتْ هَذِهِ الآيَةُ : ( يا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَرْفَعُوا أَصْوَاتَكُمْ فَوْقَ صَوْتِ النَّبِيِّ ) فَكَانَ عُمَرُ بْنُ الْخَطَّابِ بَعْدَ ذَلِكَ إِذَا تَكَلَّمَ عِنْدَ النَّبِيِّ ﷺ لَمْ يُسْمِعْ كَلاَمَهُ حَتَّى يَسْتَفْهِمَهُ . قَالَ وَمَا ذَكَرَ ابْنُ الزُّبَيْرِ جَدَّهُ يَعْنِي أَبَا بَكْرٍ .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ . وَقَدْ رَوَى بَعْضُهُمْ عَنِ ابْنِ أَبِي مُلَيْكَةَ مُرْسَلٌ وَلَمْ يَذْكُرْ فِيهِ عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ .
