Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ قَالَ سَمِعْتُ عَلِيَّ بْنَ زَيْدٍ يُحَدِّثُ عَنِ النَّضْرِ بْنِ أَنَسٍ قَالَ مَاتَ لِأَنَسٍ وَلَدٌ فَكَتَبَ إِلَيْهِ زَيْدُ بْنُ أَرْقَمَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اللَّهُمَّ اغْفِرْ لِلْأَنْصَارِ وَلِأَبْنَاءِ الْأَنْصَارِ وَلِأَبْنَاءِ أَبْنَاءِ الْأَنْصَارِ.
English Translation
Muhammad ibn Ja'far told us: Shu'bah told us, who said: I heard Ali ibn Zayd narrate from al-Nadr ibn Anas, who said: A child of Anas died, so Zayd ibn Arqam wrote to him: that the Messenger of Allah, peace and blessings be upon him, said: O Allah, forgive the Ansar, the children of the Ansar, and the children of the children of the Ansar.
