Mukhtasar Bukhari

Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that (one day) the Noble Prophet (peace and blessings of Allah be upon him) ascended the pulpit, and it was the last gathering in which the Messenger of Allah (peace and blessings of Allah be upon him) sat. He (peace and blessings of Allah be upon him) had a large cloak draped over his shoulders and had tied his blessed head with a dusty-colored band. Then he (peace and blessings of Allah be upon him) said: "O people! Come near to me." So the people gathered close to him (peace and blessings of Allah be upon him). After that, he (peace and blessings of Allah be upon him) said: "To proceed! This tribe of Ansar will keep decreasing, and other people will keep increasing. Therefore, whoever among the Ummah possesses anything and has the authority by which he can harm or benefit someone, he should accept the good deeds of the righteous among them (i.e., the Ansar) and overlook the mistakes of the wrongdoers among them."
