(43) باب مِنْ فَضَائِلِ الأَنْصَارِ رضى الله تعالى عنهم
Anas b. Malik reported Allah's Messenger (ﷺ) as saying:
The Ansar are my family and my trusted friends. and the people would increase in number whereas they (the Ansar) would become less and less, so appreciate the deeds of those from amongst them who do good and overlook their failings.
