It was narrated that Qais bin Talq said:"My father, Talq bin 'Ali visited me one day in Ramadan and stayed with us until the evening. He led us in praying Qiyam that night and prayed witr with us. Then he went down to a masjid and led his companions in prayer until only witr was left. Then he told a man to go forward and said to him: 'Lead them in praying witr, for I heard the Messenger of Allah (ﷺ) say: There should not be two witrs in one night."
أَخْبَرَنَا هَنَّادُ بْنُ السَّرِيِّ، عَنْ مُلاَزِمِ بْنِ عَمْرٍو، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ بَدْرٍ، عَنْ قَيْسِ بْنِ طَلْقٍ، قَالَ زَارَنَا أَبِي طَلْقُ بْنُ عَلِيٍّ فِي يَوْمٍ مِنْ رَمَضَانَ فَأَمْسَى بِنَا وَقَامَ بِنَا تِلْكَ اللَّيْلَةَ وَأَوْتَرَ بِنَا ثُمَّ انْحَدَرَ إِلَى مَسْجِدٍ فَصَلَّى بِأَصْحَابِهِ حَتَّى بَقِيَ الْوِتْرُ ثُمَّ قَدَّمَ رَجُلاً فَقَالَ لَهُ أَوْتِرْ بِهِمْ فَإِنِّي سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ وِتْرَانِ فِي لَيْلَةٍ " .
