It is narrated from Sayyiduna Uqbah (may Allah be pleased with him), the father of Abd al-Rahman (he had been struck by an arrow while with the Prophet (peace and blessings be upon him)). He said: I heard the Prophet (peace and blessings be upon him) say: "No Muslim will enter the Fire who saw me, or saw someone who saw me, or saw someone who saw someone who saw me." He (peace and blessings be upon him) said this three times.
