Narrated Kharija bin Zaid bin Thabit: Um Al-`Ala an Ansari woman who had given a pledge of allegiance to Allah's Apostle told me:, "The Muhajirln (emigrants) were distributed amongst us by drawing lots, and we got `Uthman bin Maz'un in our share. We made him stay with us in our house. Then he suffered from a disease which proved fatal. When he died and was given a bath and was shrouded in his clothes. Allah's Apostle came, I said, (addressing the dead body), 'O Aba As-Sa'ib! May Allah be Merciful to you! I testify that Allah has honored you.' Allah's Apostle said, 'How do you know that Allah has honored him?" I replied, 'Let my father be sacrificed for you, O Allah's Apostle! On whom else shall Allah bestow. His honor?' Allah's Apostle said, 'As for him, by Allah, death has come to him. By Allah, I wish him all good (from Allah). By Allah, in spite of the fact that I am Allah's Apostle, I do not know what Allah will do to me.", Um Al-`Ala added, "By Allah, I will never attest the righteousness of anybody after that."

Narrated Az-Zuhri: Regarding the above narration, The Prophet said, "I do not know what Allah will do to him (Uthman bin Maz'un)." Um Al-`Ala said, "I felt very sorry for that, and then I slept and saw in a dream a flowing spring for `Uthman bin Maz'un, and told Allah's Apostle of that, and he said, "That flowing spring symbolizes his good deeds."
