Authentic hadithعن زيد بن أرقم رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم : «اللهمَّ اغفِرْ للأنصار، ولأبناءِ الأنصار، وأبناءِ أبناءِ الأنصار».
Zayd ibn Arqam (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: ''O Allah, forgive the Ansār, the offspring of the Ansār, and the offspring of the offspring of the Ansār.''
Explanation
In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) invoked divine forgiveness on the Ansār, their children, and their grandchildren. This indicates an evident virtue of the Ansār and their progeny after them.
