[Machine] I prayed the Maghrib prayer with the Prophet ﷺ and he performed the salaam in the two units (rak'ahs), then he left. A man said to him, "O Messenger of Allah, you have made a mistake as you performed the salaam in two units." So he commanded Bilal to establish the prayer and then completed that unit. The people asked about the man who said, "O Messenger of Allah, you have made a mistake." It was said, "Do you know him?" I said, "I do not know him, unless I see him." So he passed by me and I said, "This is him." They said, "This is Talhah bin 'Ubaidullah."  

صَلَّيْتُ مَعَ النَّبِيِّ ﷺ الْمَغْرِبَ فَسَهَا وَسَلَّمَ فِي الرَّكْعَتَيْنِ ثُمَّ انْصَرَفَ فَقَالَ لَهُ رَجُلٌ يَا رَسُولَ اللهِ إِنَّكَ سَهَوْتَ فَسَلَّمْتَ فِي رَكْعَتَيْنِ فَأَمَرَ بِلَالًا فَأَقَامَ الصَّلَاةَ ثُمَّ أَتَمَّ تِلْكَ الرَّكْعَةَ فَسَأَلَهُ النَّاسُ عَنِ الرَّجُلِ الَّذِي قَالَ يَا رَسُولَ اللهِ إِنَّكَ سَهَوْتَ فَقِيلَ تَعْرِفُهُ؟ فَقُلْتُ لَا إِلَّا أَنْ أَرَاهُ فَمَرَّ بِي فَقُلْتُ هُوَ هَذَا قَالُوا هَذَا طَلْحَةُ بْنُ عُبَيْدِ اللهِ
