It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "What a good man I am for the worst of my Ummah!" A man from among those sitting with him (peace and blessings be upon him) said: O Messenger of Allah, then how are you for the best of them? He (peace and blessings be upon him) said: "As for the worst of my Ummah, Allah will admit them into Paradise through my intercession, and as for the best of them, Allah will admit them into Paradise through their deeds."
