Narrated Abu Huraira:

I have not ceased to like Banu Tamim ever since I heard of three qualities attributed to them by Allah's Messenger (He said): They, out of all my followers, will be the strongest opponent of Ad-Dajjal; `Aisha 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."

حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا جَرِيرٌ، عَنْ عُمَارَةَ بْنِ الْقَعْقَاعِ، عَنْ أَبِي زُرْعَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ لاَ أَزَالُ أُحِبُّ بَنِي تَمِيمٍ بَعْدَ ثَلاَثٍ سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم 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 ‏"‏‏.‏
