Sayyidina Imran ibn Husayn (RA) reported that a deputation of Banu Tamim came to Allah’s Messenger who said, “Glad tidings, O Banu Tamim!” They said, “Since you give us glad tidings, do grant us something, too!” The narrator reported that the face of Allah’s Messenger ﷺ changed colour. Also, a deputation of the people of Yemen came (to him) and he said, “Accept the glad tidings that Banu Tamim did not accept.” They said, “Indeed, we accept (it).” [Ahmed 19897, Bukhari 3191] --------------------------------------------------------------------------------
