Sunan an-Nasa'i, Hadith 2073 ⓘ
Ka 'b bin Malik used to narrate that the Messenger of Allah said: "The soul of the belevier is (like a bird) flying among the trees of Paradise, until Allah, the Mighty and sublime, sends it back to his body on the Day of Resurrection." (Da 'if)
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ كَعْبٍ، أَنَّهُ أَخْبَرَهُ أَنَّ أَبَاهُ كَعْبَ بْنَ مَالِكٍ كَانَ يُحَدِّثُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّمَا نَسَمَةُ الْمُؤْمِنِ طَائِرٌ فِي شَجَرِ الْجَنَّةِ حَتَّى يَبْعَثَهُ اللَّهُ عَزَّ وَجَلَّ إِلَى جَسَدِهِ يَوْمَ الْقِيَامَةِ " .
