Yahya related to me from Malik from Ibn Shihab that Abd ar-Rahman ibn Kab ibn Malik al-Ansari told him that his father, Kab ibn Malik, used to relate that the Messenger of Allah ﷺ said, "The ruh of the mumin is a bird that sits in the trees of the Garden until Allah returns it to his body on the day He raises him ."
مَالِكٍ كَانَ يُحَدِّثُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِنَّمَا نَسَمَةُ الْمُؤْمِنِ طَيْرٌ يَعْلَقُ فِي شَجَرِ الْجَنَّةِ حَتَّى يَرْجِعَهُ اللَّهُ إِلَى جَسَدِهِ يَوْمَ يَبْعَثُهُ
