I have not ceased to like Banu Tamim ever since I heard of three qualities attributed to them by Messenger of Allah ﷺ (He said): They, out of all my followers, will be the strongest opponent of Ad-Dajjal; ʿAisha had a slave-girl from them, and the Prophet ﷺ told her to manumit her as she was from the descendants of (the Prophet) Ishmael; and, when their Zakat was brought, the Prophet ﷺ said, "This is the Zakat of my people."  

لاَ أَزَالُ أُحِبُّ بَنِي تَمِيمٍ بَعْدَ ثَلاَثٍ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ يَقُولُهَا فِيهِمْ هُمْ أَشَدُّ أُمَّتِي عَلَى الدَّجَّالِ وَكَانَتْ فِيهِمْ سَبِيَّةٌ عِنْدَ عَائِشَةَ فَقَالَ أَعْتِقِيهَا فَإِنَّهَا مِنْ وَلَدِ إِسْمَاعِيلَ وَجَاءَتْ صَدَقَاتُهُمْ فَقَالَ هَذِهِ صَدَقَاتُ قَوْمٍ أَوْ قَوْمِي  

ʿAbdullah bin Az-Zubair said that a group of riders belonging to Banu Tamim came to the Prophet, Abu Bakr said (to the Prophet ﷺ ), "Appoint Al-Qa'qa bin Mabad bin Zurara as (their) ruler." ʿUmar said (to the Prophet). "No! But appoint Al-Aqra bin HʿAbis." Thereupon Abu Bakr said (to ʿUmar). "You just wanted to oppose me." ʿUmar replied. "I did not want to oppose you." So both of them argued so much that their voices became louder, and then the following Divine Verses were revealed in that connection:-- "O you who believe ! Do not be forward in the presence of Allah and His Apostle..." (till the end of Verse)...(49.1)  

أَنَّهُ قَدِمَ رَكْبٌ مِنْ بَنِي تَمِيمٍ عَلَى النَّبِيِّ ﷺ فَقَالَ أَبُو بَكْرٍ أَمِّرِ الْقَعْقَاعَ بْنَ مَعْبَدِ بْنِ زُرَارَةَ قَالَ عُمَرُ بَلْ أَمِّرِ الأَقْرَعَ بْنَ حَابِسٍ قَالَ أَبُو بَكْرٍ مَا أَرَدْتَ إِلاَّ خِلاَفِي قَالَ عُمَرُ مَا أَرَدْتُ خِلاَفَكَ فَتَمَارَيَا حَتَّى ارْتَفَعَتْ أَصْوَاتُهُمَا فَنَزَلَ فِي ذَلِكَ {يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تُقَدِّمُوا} حَتَّى انْقَضَتْ
