Abdur Rahman bin Amr and Hujr bin Hujr say that we came to Sayyiduna Irbad bin Sariyah (may Allah be pleased with him) (about whom this verse was revealed): "There is no blame upon those who come to you so that you may mount them..." We greeted him with salam and said, "We have come to meet you, to visit you, and to benefit from you." He said: Once the Prophet (peace and blessings be upon him) led us in the Fajr prayer, then turned to us and gave such an admonition that people's eyes began to weep and hearts began to tremble. We said, "O Messenger of Allah! This seems like a farewell admonition, so what do you enjoin upon us?" The Prophet (peace and blessings be upon him) said: "I am leaving you upon a clear path, whose night and day are alike. Whoever deviates from it after me will be destroyed. And whoever among you lives (after me) will soon see many differences, so hold fast to my Sunnah and the Sunnah of the rightly guided Caliphs, and cling to it firmly. And make obedience to the leader obligatory upon yourselves, even if he is an Abyssinian slave. Hold on to these things firmly, and beware of newly invented matters, for every newly invented matter is an innovation, and every innovation is misguidance."
