O Allah,, grant forgiveness to the Ansar, the offspring of the Ansar and the offspring of the offspring of the Ansar. This hadith has been narrated on the authority of Shulba with the same chain of transmitters.  

مسلم:٢٥٠٦aحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ وَعَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ قَالاَ حَدَّثَنَا شُعْبَةُ عَنْ قَتَادَةَ عَنِ النَّضْرِ بْنِ أَنَسٍ عَنْ زَيْدِ بْنِ أَرْقَمَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ اللَّهُمَّ اغْفِرْ لِلأَنْصَارِ وَلأَبْنَاءِ الأَنْصَارِ وَأَبْنَاءِ أَبْنَاءِ الأَنْصَارِ وَحَدَّثَنِيهِ يَحْيَى بْنُ حَبِيبٍ حَدَّثَنَا خَالِدٌ يَعْنِي ابْنَ الْحَارِثِ حَدَّثَنَا شُعْبَةُ بِهَذَا الإِسْنَادِ
