مُسْنَدُ عُثْمَانَ بْنِ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ

Musnad Uthman ibn Affan
Musnad Ahmad 427, 428
It was narrated that Abu `Ubaid said:
I saw `Ali and `Uthman (رضي الله عنه)on the day of (Eid) al-fitr and (Eid) al-Adhaa; they prayed, then when they finished they reminded the people. I heard them saying. The Messenger of Allah (ﷺ) forbade fasting on these two days,

It was narrated from `Ata` bin Yazeed al-Junda`i that he heard Humran the freed slave of `Uthman bin `Affan (رضي الله عنه), say. I saw Ameer al-Mu`mineen `Uthman do wudoo’; he poured water onto his hands three times, then he rinsed his nose three times and rinsed his mouth three times... and he mentioned the Hadeeth, similar to the Hadeeth of Ma`mar.

حَدَّثَنَا عَبْد اللَّهِ، حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي بَكْرٍ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، عَنْ سَعِيدِ بْنِ عَبْدِ اللَّهِ بْنِ قَارِظٍ، عَنْ أَبِي عُبَيْدٍ، قَالَ شَهِدْتُ عَلِيًّا وَعُثْمَانَ رَضِيَ اللَّهُ عَنْهُمَا فِي يَوْمِ الْفِطْرِ وَالنَّحْرِ يُصَلِّيَانِ ثُمَّ يَنْصَرِفَانِ فَيُذَكِّرَانِ النَّاسَ فَسَمِعْتُهُمَا يَقُولَانِ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ صَوْمِ هَذَيْنِ الْيَوْمَيْنِ حَدَّثَنَا مُحَمَّدُ بْنُ بَكْرٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ حَدَّثَنِي ابْنُ شِهَابٍ عَنْ عَطَاءِ بْنِ يَزِيدَ الْجُنْدَعِيِّ أَنَّهُ سَمِعَ حُمْرَانَ مَوْلَى عُثْمَانَ بْنِ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ قَالَ رَأَيْتُ أَمِيرَ الْمُؤْمِنِينَ عُثْمَانَ يَتَوَضَّأُ فَأَهْرَاقَ عَلَى يَدَيْهِ ثَلَاثَ مَرَّاتٍ ثُمَّ اسْتَنْثَرَ ثَلَاثَ مَرَّاتٍ وَمَضْمَضَ ثَلَاثًا وَذَكَرَ الْحَدِيثَ مِثْلَ مَعْنَى حَدِيثِ مَعْمَرٍ‏.‏
