[Machine] Mother to Mubashshir: Read, my son, Mubashshir, the greeting of peace from me. He replied: Ka'b said, "That is not what the Messenger of Allah ﷺ said. The Messenger of Allah ﷺ said, 'The souls of the martyrs are in green birds, hanging wherever they wish.'" She said, "Indeed, I seek forgiveness from Allah." He said, "That is how I heard it."  

الطبراني:١٦٢٣٦ – حَدَّثَنَا أَحْمَدُ بْنُ عَمْرٍو الْخَلَّالُ الْمَكِّيُّ ثنا يَعْقُوبُ بْنُ حُمَيْدٍ ثنا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ عَمْرِو بْنِ دِينَارٍ عَنِ ابْنِ شِهَابٍ الزُّهْرِيِّ عَنْ ابْنَ كَعْبِ بْنِ مَالِكٍ عَنْ أَبِيهِ أَنَّ رَجُلًا مِنَ الْأَنْصَارِ هَلَكَ فَقَالَتْ

أُمُّ مُبَشِّرٍ أَقْرِئِ ابْنِي مُبَشِّرًا مِنِّي السَّلَامَ فَقَالَ كَعْبٌ لَيْسَ هَكَذَا قَالَ رَسُولُ اللهِ ﷺ إِنَّمَا قَالَ رَسُولُ اللهِ ﷺ «أَرْوَاحُ الشُّهَدَاءِ فِي طَيْرٍ خَضِرٍ تَعْلُقُ حَيْثُ شَاءَتْ» قَالَتْ فَإِنِّي أَسْتَغْفِرُ اللهَ قَالَ «هَكَذَا سَمِعْتُهُ»
