Sayyiduna Ibn Abbas (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) (during the days of his final illness) came out with a cloth wrapped around his head and face and said: O people! The general populace is increasing in number while the Ansar are decreasing in number, so whoever among you attains authority over the affairs (of leadership) and is able to benefit someone, he should accept the words of the virtuous among the Ansar, and if any of them makes a mistake, he should overlook it.
