I have loved the people of the tribe of Bani Tamim ever since I heard, three things, Messenger of Allah 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, Messenger of Allah ﷺ said, "These are the Sadaqat (i.e. charitable gifts) of our folk." ʿAisha had a slave-girl from that tribe, and the Prophet ﷺ said to ʿAisha, "Manumit her as she is a descendant of Ishmael (the Prophet).
