[Machine] A group of riders from the tribe of Banu Tamim came to the Prophet Muhammad ﷺ , among them was Al-Aqra' bin Habis. Abu Bakr said, "O Messenger of Allah, appoint Al-Aqra' to lead his people." Umar said, "O Messenger of Allah, do not appoint him, as they may start arguing." They continued to argue until their voices got raised. At that moment, the verse was revealed: "O you who have believed, do not put [yourselves] before Allah and His Messenger." And the verse was completed.
أَنَّهُ قَدِمَ رَكِبٌ مِنْ بَنِي تَمِيمٍ عَلَى النَّبِيِّ ﷺ فِيهِمْ الْأَقْرَعُ بْنُ حَابِسٍ فَقَالَ أَبُو بَكْرٍ يَا رَسُولَ اللهِ اسْتَعْمِلْ الْأَقْرَعَ عَلَى قَوْمِهِ فَقَالَ عُمَرُ يَا رَسُولَ اللهِ لَا تَسْتَعْمِلْهُ فَتَنَازَعَا حَتَّى ارْتَفَعَتْ أَصْوَاتُهُمَا فَنَزَلَ فِي ذَلِكَ {يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تُقَدِّمُوا بَيْنَ يَدَيِ اللهِ وَرَسُولِهِ} حَتَّى انْقَضَتِ الْآيَةُ
