Ziyad bin Alaqah (may Allah have mercy on him) says that on the day Hazrat Mughirah bin Shu’bah (may Allah be pleased with him) passed away, Hazrat Jarir bin Abdullah (may Allah be pleased with him) stood up to deliver a sermon. I heard him say: Fear Allah and remain dignified and calm until your next leader arrives, for your leader will surely come. Then he said: Intercede before your leader, for he likes to pardon. And after saying "Amma ba'd," he said: Once I presented myself before the Prophet Muhammad (peace and blessings be upon him) and said that I pledge allegiance to you on Islam. The Prophet (peace and blessings be upon him) made it a condition for me to wish well for every Muslim. I pledged allegiance to the Prophet (peace and blessings be upon him) on this condition. By the Lord of this mosque! I am a well-wisher for all of you.
