Sunan an-Nasa'i, Volume 2, Book 12, Hadith 1166 (DarusSalam) ⓘ
Yahya-Ibn Adam- said: "I heard Sufyan reciting this tashahhud in the obligatory and voluntary prayers, and he said: 'Abu Ishaq narrated to us from Abu Al-Ahwas from Abdullah, from the Prophet.'" And Mansur and Hammad narrated to us from Abu Wa'il, from Abdullah, from the Prophet.
أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا يَحْيَى، - وَهُوَ ابْنُ آدَمَ - قَالَ سَمِعْتُ سُفْيَانَ، يَتَشَهَّدُ بِهَذَا فِي الْمَكْتُوبَةِ وَالتَّطَوُّعِ وَيَقُولُ حَدَّثَنَا أَبُو إِسْحَاقَ عَنْ أَبِي الأَحْوَصِ عَنْ عَبْدِ اللَّهِ عَنِ النَّبِيِّ صلى الله عليه وسلم ح وَحَدَّثَنَا مَنْصُورٌ وَحَمَّادٌ عَنْ أَبِي وَائِلٍ عَنْ عَبْدِ اللَّهِ عَنِ النَّبِيِّ صلى الله عليه وسلم .
