Jami` at-Tirmidhi, Book 49, Hadith 4067 (In-Book) ⓘ
Narrated Anas bin Malik: that when the Messenger of Allah ordered the pledge of Ridwan, 'Uthman bin 'Affan was the messenger of the Messenger of Allah to the people of Makkah. He said: "So the Messenger of Allah said: 'Indeed 'Uthman is busy with the affair of Allah and the affair of His Messenger' then he put one of his hands on the other. The hand of the Messenger of Allah on behalf of 'Uthman, was better than their own hands for themselves.
حَدَّثَنَا أَبُو زُرْعَةَ، حَدَّثَنَا الْحَسَنُ بْنُ بِشْرٍ، حَدَّثَنَا الْحَكَمُ بْنُ عَبْدِ الْمَلِكِ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ لَمَّا أُمِرَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِبَيْعَةِ الرِّضْوَانِ كَانَ عُثْمَانُ بْنُ عَفَّانَ رَسُولَ رَسُولِ اللَّهِ صلى الله عليه وسلم إِلَى أَهْلِ مَكَّةَ قَالَ فَبَايَعَ النَّاسَ قَالَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ عُثْمَانَ فِي حَاجَةِ اللَّهِ وَحَاجَةِ رَسُولِهِ " . فَضَرَبَ بِإِحْدَى يَدَيْهِ عَلَى الأُخْرَى فَكَانَتْ يَدُ رَسُولِ اللَّهِ صلى الله عليه وسلم لِعُثْمَانَ خَيْرًا مِنْ أَيْدِيهِمْ لأَنْفُسِهِمْ . قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ غَرِيبٌ .
