Sahih Bukhari Volume 2, Book 23, Hadith 1244

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، حَدَّثَنَا اللَّيْثُ، عَنْ عُقَيْلٍ، عَنِ ابْنِ شِهَابٍ، قَالَ أَخْبَرَنِي خَارِجَةُ بْنُ زَيْدِ بْنِ ثَابِتٍ، أَنَّ أُمَّ الْعَلاَءِ ـ امْرَأَةً مِنَ الأَنْصَارِ ـ بَايَعَتِ النَّبِيَّ صلى الله عليه وسلم أَخْبَرَتْهُ أَنَّهُ اقْتُسِمَ الْمُهَاجِرُونَ قُرْعَةً فَطَارَ لَنَا عُثْمَانُ بْنُ مَظْعُونٍ، فَأَنْزَلْنَاهُ فِي أَبْيَاتِنَا، فَوَجِعَ وَجَعَهُ الَّذِي تُوُفِّيَ فِيهِ، فَلَمَّا تُوُفِّيَ وَغُسِّلَ وَكُفِّنَ فِي أَثْوَابِهِ، دَخَلَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقُلْتُ رَحْمَةُ اللَّهِ عَلَيْكَ أَبَا السَّائِبِ، فَشَهَادَتِي عَلَيْكَ لَقَدْ أَكْرَمَكَ اللَّهُ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ وَمَا يُدْرِيكِ أَنَّ اللَّهَ قَدْ أَكْرَمَهُ ‏"‏‏.‏ فَقُلْتُ بِأَبِي أَنْتَ يَا رَسُولَ اللَّهِ فَمَنْ يُكْرِمُهُ اللَّهُ فَقَالَ ‏"‏ أَمَّا هُوَ فَقَدْ جَاءَهُ الْيَقِينُ، وَاللَّهِ إِنِّي لأَرْجُو لَهُ الْخَيْرَ، وَاللَّهِ مَا أَدْرِي ـ وَأَنَا رَسُولُ اللَّهِ ـ مَا يُفْعَلُ بِي ‏"‏‏.‏ قَالَتْ فَوَاللَّهِ لاَ أُزَكِّي أَحَدًا بَعْدَهُ أَبَدًا‏ حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ، حَدَّثَنَا اللَّيْثُ، مِثْلَهُ‏.‏ وَقَالَ نَافِعُ بْنُ يَزِيدَ عَنْ عُقَيْلٍ، مَا يُفْعَلُ بِهِ وَتَابَعَهُ شُعَيْبٌ وَعَمْرُو بْنُ دِينَارٍ وَمَعْمَرٌ‏

Narrated By Kharija bin Zaid bin Thabit : Um Al-'Ala', an Ansari woman who gave the pledge of allegiance to the Prophet said to me, "The emigrants were distributed amongst us by drawing lots and we got in our share 'Uthman bin Maz'un. 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, 'May Allah be merciful to you, O Abu As-Sa'ib! I testify that Allah has honoured you'. The Prophet said, 'How do you know that Allah has honoured him?' I replied, 'O Allah's Apostle! Let my father be sacrificed for you! On whom else shall Allah bestow His honour?' The Prophet said, 'No doubt, death came to him. By Allah, I too wish him good, but by Allah, I do not know what Allah will do with me though I am Allah's Apostle.' By Allah, I never attested the piety of anyone after that."
