The Messenger of Allah ﷺ said, "The Ansar are my close confidants and trusted ones. People will increase in number, while they will diminish. So accept from those of them who do good, and overlook the faults of those who err."
قال رسول الله ﷺ: الأنصار كرشي وعيبتي، وإن الناس يكثرون، وهو يقلون، فاقبلوا من محسنهم، وتجاوزوا عن مسيئهم.
