Musnad Ahmad 2614

It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The Messenger of Allah (ﷺ) went out, covering his head with his garment, and said: “O people, the people are increasing in number and the Ansar are decreasing. Whoever attains a position of authority in which he is able to benefit anyone, let him accept the good deeds of those who do good and overlook their bad deeds.”
