Narrated Um Al-Ala: That when the Ansar drew lots as to which of the emigrants should dwell with which of the Ansar, the name of `Uthman bin Mazun came out (to be in their lot). Um Al-Ala further said, "Uthman stayed with us, and we nursed him when he got sick, but he died. We shrouded him in his clothes, and Allah's Apostle came to our house and I said, (addressing the dead `Uthman), 'O Abu As-Sa'ib! May Allah be merciful to you. I testify that Allah has blessed you.' The Prophet (ﷺ) said to me, "How do you know that Allah has blessed him?" I replied, 'I do not know O Allah's Messenger (ﷺ)! May my parents be sacrificed for you.' Allah's Messenger (ﷺ) said, 'As regards `Uthman, by Allah he has died and I really wish him every good, yet, by Allah, although I am Allah's Messenger (ﷺ), I do not know what will be done to me.' Um Al- Ala added, 'By Allah I shall never attest the piety of anybody after him. And what Allah's Messenger (ﷺ)s said made me sad." Um Al-Ala further said, "Once I slept and saw in a dream, a flowing stream for `Uthman. So I went to Allah's Messenger (ﷺ) and told him about it, he said, 'That is (the symbol of) his deeds."
Narrated Kharija bin Zaid bin Thabit: Um Al-`Ala an Ansari woman who had given the Pledge of allegiance to Allah's Messenger (ﷺ) said, "`Uthman bin Maz'un came in our share when the Ansars drew lots to distribute the emigrants (to dwell) among themselves, He became sick and we looked after (nursed) him till he died. Then we shrouded him in his clothes. Allah's Messenger (ﷺ) came to us, I (addressing the dead body) said, "May Allah's Mercy be on you, O Aba As-Sa'ib! I testify that Allah has honored you." The Prophet (ﷺ) said, 'How do you know that?' I replied, 'I do not know, by Allah.' He said, 'As for him, death has come to him and I wish him all good from Allah. By Allah, though I am Allah's Messenger (ﷺ), I neither know what will happen to me, nor to you.'" Um Al-`Ala said, "By Allah, I will never attest the righteousness of anybody after that." She added, "Later I saw in a dream, a flowing spring for `Uthman. So I went to Allah's Messenger (ﷺ) and mentioned that to him. He said, 'That is (the symbol of) his good deeds (the reward for) which is going on for him.' "
