Abu Huraira reported: Since I heard three things from Messenger of Allah ﷺ my love for Banu Tamim is never on the decline (and these things are): I heard Messenger of Allah ﷺ as saying about them that they would put up stout resistance against Dajjal amongst my Umma. And he (the narrator) said: (When) the consignment of Zakat was brought to him, Messenger of Allah ﷺ said: This is the charity of our people, and there was one slave-girl in the house of 'A'isha and she was from the tribe of Banu Tamim;
thereupon Messenger of Allah ﷺ said: Set her free, for she is from the offspring of Isma'il. The other hadith has been transmitted on the authority of Abu Huraira with a slight variation of wording.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا جَرِيرٌ، عَنْ مُغِيرَةَ، عَنِ الْحَارِثِ، عَنْ أَبِي زُرْعَةَ، قَالَ قَالَ أَبُو هُرَيْرَةَ لاَ أَزَالُ أُحِبُّ بَنِي تَمِيمٍ مِنْ ثَلاَثٍ سَمِعْتُهُنَّ مِنْ، رَسُولِ اللَّهِ ﷺ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ " هُمْ أَشَدُّ أُمَّتِي عَلَى الدَّجَّالِ " . قَالَ وَجَاءَتْ صَدَقَاتُهُمْ فَقَالَ النَّبِيُّ ﷺ " هَذِهِ صَدَقَاتُ قَوْمِنَا " . قَالَ وَكَانَتْ سَبِيَّةٌ مِنْهُمْ عِنْدَ عَائِشَةَ فَقَالَ رَسُولُ اللَّهِ ﷺ " أَعْتِقِيهَا فَإِنَّهَا مِنْ وَلَدِ إِسْمَاعِيلَ " .
