It was narrated from ‘Abdur-Rahman bin Ka’b Al-Ansari that his father used to narrate that the Messenger of Allah ﷺ said:
“The believer’s soul is a bird that eats from the trees of Paradise, until it will be returned to his body on the Day when he is resurrected.”

حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، أَنْبَأَنَا مَالِكُ بْنُ أَنَسٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبٍ الأَنْصَارِيِّ، أَنَّهُ أَخْبَرَهُ أَنَّ أَبَاهُ كَانَ يُحَدِّثُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ : " إِنَّمَا نَسَمَةُ الْمُؤْمِنِ طَائِرٌ يَعْلُقُ فِي شَجَرِ الْجَنَّةِ حَتَّى يَرْجِعَ إِلَى جَسَدِهِ يَوْمَ يُبْعَثُ " .
