Sayyiduna Abu Dharr (may Allah be pleased with him) said: "On the Day of Resurrection I will be the closest of you to the Messenger of Allah (peace and blessings be upon him). He (peace and blessings be upon him) departed from this world in the same state that I am in as well; and by Allah, I have not introduced anything new (into the religion) after him (peace and blessings be upon him); and there is not one of you except that he has clung to something of this world."
