[Machine] I said, "I will surpass everyone in the night prayer tonight." So I went ahead of them. While I was standing and praying, suddenly someone placed his hand on my back. I looked and saw it was Uthman ibn Affan, who was the Amir (leader) at that time. So I stepped aside. He stood and began reciting the Qur'an until he finished it, then he performed a bowing (rak'ah) and sat down, recited the testimony of faith, and greeted in a single bowing (rak'ah) without adding extra. When he finished, I said, "O Amir al-Mu'minin (Commander of the Faithful), you only prayed one bowing (rak'ah)." He replied, "It is my odd (witr) prayer." And among them is Sa'd ibn Abi Waqqas.  

قُلْتُ لَأَغْلِبَنَّ عَلَى الْمَقَامِ اللَّيْلَةَ فَسَبَقْتُ إِلَيْهِ فَبَيْنَمَا أَنَا قَائِمٌ أُصَلِّي إِذَا رَجُلٌ وَضَعَ يَدَهُ عَلَى ظَهْرِي قَالَ فَنَظَرْتُ فَإِذَا عُثْمَانُ بْنُ عَفَّانَ ؓ وَهُوَ يَوْمَئِذٍ أَمِيرٌ فَتَنَحَّيْتُ عَنْهُ فَقَامَ فَافْتَتَحَ الْقُرْآنَ حَتَّى فَرَغَ مِنْهُ ثُمَّ رَكَعَ وَجَلَسَ وَتَشَهَّدَ وَسَلَّمَ فِي رَكْعَةٍ وَاحِدَةٍ لَمْ يَزِدْ عَلَيْهَا فَلَمَّا انْصَرَفَ قُلْتُ يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّمَا صَلَّيْتَ رَكْعَةً قَالَ هِيَ وِتْرِي وَمِنْهُمْ سَعْدُ بْنُ أَبِي وَقَّاصٍ ؓ
