It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever meets Allah Almighty in the state that he did not make anything equal to Allah in the world, and then he has sins like the mountains upon him, Allah will forgive him."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Umarah except al-Darawardi, and this hadith is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) only with this chain."
