حَدَّثَنَا حَسَنُ بْنُ مُوسَى حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ عَنْ عَلِيِّ بْنِ زَيْدٍ عَنِ النَّضْرِ بْنِ أَنَسٍ أَنَّ زَيْدَ بْنَ أَرْقَمَ كَتَبَ إِلَى أَنَسِ بْنِ مَالِكٍ زَمَنَ الْحَرَّةِ يُعَزِّيهِ فِيمَنْ قُتِلَ مِنْ وَلَدِهِ وَقَوْمِهِ وَقَالَ أُبَشِّرُكَ بِبُشْرَى مِنْ اللَّهِ عَزَّ وَجَلَّ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ اللَّهُمَّ اغْفِرْ لِلْأَنْصَارِ وَلِأَبْنَاءِ الْأَنْصَارِ وَلِأَبْنَاءِ أَبْنَاءِ الْأَنْصَارِ وَاغْفِرْ لِنِسَاءِ الْأَنْصَارِ وَلِنِسَاءِ أَبْنَاءِ الْأَنْصَارِ وَلِنِسَاءِ أَبْنَاءِ أَبْنَاءِ الْأَنْصَارِ.
English Translation
Hasan ibn Musa told us: Hammad ibn Salamah told us, from Ali ibn Zayd, from al-Nadr ibn Anas: that Zayd ibn Arqam wrote to Anas ibn Malik at the time of the Battle of al-Harrah, consoling him for those killed among his children and his people, and said: I bring you glad tidings from Allah, Mighty and Majestic — I heard the Messenger of Allah, peace and blessings be upon him, say: O Allah, forgive the Ansar, the children of the Ansar, and the children of the children of the Ansar.
