It was narrated from ‘Abdur-Rahman bin Ka’b bin Malik, about Ka’b: “When Ka’b was dying, Umm Bishr bint Bara’ bin Ma’rur came to him and said: ‘O Abu ‘Abdur-Rahman! If you meet so-and-so, convey Salam to him from me.’ He said: ‘May Allah forgive you, O Umm Bishr! We are too busy to think of that.’ She said: ‘O Abu ‘Abdur-Rahman! Did you not hear the Messenger of Allah (ﷺ) say: “The souls of the believers are in green birds, eating from the trees of Paradise”?’ He said: ‘Yes.’ She said: ‘That is what I mean.’”
