Mishkat al-Masabih 30 Fine Qualities كتاب المناقب 91

وَعَن أنسٍ قَالَ: لَمَّا أَمَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِبَيْعَةِ الرِّضْوَانِ كَانَ عُثْمَانُ رَضِيَ اللَّهُ عَنْهُ رَسُولُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِلَى مَكَّةَ فَبَايَعَ النَّاسُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِن عُثْمَانَ فِي حَاجَةِ اللَّهِ وَحَاجَةِ رَسُولِهِ» فَضَرَبَ بِإِحْدَى يَدَيْهِ عَلَى الْأُخْرَى فَكَانَتْ يَدُ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِعُثْمَانَ خَيْرًا من أَيْديهم لأَنْفُسِهِمْ. رَوَاهُ التِّرْمِذِيّ

Anas said: When God’s messenger gave orders for the oath of allegiance of God’s good pleasure[*] `Uthman had gone to Mecca as God’s messenger’s messenger. Then when the people had taken the oath of allegiance God’s messenger said, “`Uthman is engaged in God’s business and in His messenger’s business.” He then struck one of his hands on the other, and God’s messenger’s hand on behalf of `Uthman was better than the people’s hands on their own behalf. *The oath of allegiance al-Hudaibiya. Cf. Quran, 48:18 Tirmidhi transmitted it.
