(13) باب مَنْ مَلَكَ مِنَ الْعَرَبِ رَقِيقًا فَوَهَبَ وَبَاعَ وَجَامَعَ وَفَدَى وَسَبَى الذُّرِّيَّةَ
Narrated Abu Huraira:
I have loved the people of the tribe of Bani Tamim ever since I heard, three things, Allah's Messenger (ﷺ) said about them. I heard him saying, These people (of the tribe of Bani Tamim) would stand firm against Ad-Dajjal." When the Sadaqat (gifts of charity) from that tribe came, Allah's Messenger (ﷺ) said, "These are the Sadaqat (i.e. charitable gifts) of our folk." `Aisha had a slave-girl from that tribe, and the Prophet (ﷺ) said to `Aisha, "Manumit her as she is a descendant of Ishmael (the Prophet).
