Sunan Abi Dawud, Book 3, Hadith 1036 (USC-MSA) ⓘ
Narrated Hulb (Yazid) at-Ta'i: Hulb prayed along with the Prophet. He used to turn to both his sides (sometimes to the left and sometimes to the right).
حَدَّثَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ، حَدَّثَنَا شُعْبَةُ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ قَبِيصَةَ بْنِ هُلْبٍ، - رَجُلٍ مِنْ طَيِّئٍ - عَنْ أَبِيهِ، أَنَّهُ صَلَّى مَعَ النَّبِيِّ صلى الله عليه وسلم وَكَانَ يَنْصَرِفُ عَنْ شِقَّيْهِ .
