Yahya bin Ya’mar says that once I mentioned to Sayyiduna Abdullah bin Umar (may Allah be pleased with him) that we people travel to different places in the world, and we meet some of those who deny predestination (qadar). He said: When you return to those people, tell them that Ibn Umar is free from you and you are free from him. He said this three times and then narrated this tradition: Sayyiduna Umar (may Allah be pleased with him) says, One day we were sitting in the presence of the Prophet (peace and blessings be upon him) when suddenly a man came walking. Then he described his appearance. The Prophet (peace and blessings be upon him) told him twice to come closer, so he came so close that his knees touched the knees of the Prophet (peace and blessings be upon him). He said: O Messenger of Allah! Tell me, what is faith (iman)? Then the narrator mentioned the complete hadith.
