Sunan Ibn Majah, Book 2, Hadith 7 (In-Book) ⓘ
It was narrated from Jabir bin Samurah that: The Prophet used to pray Zuhr when the sun had passed its zenith.
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، أَنَّ النَّبِيَّ ـ صلى الله عليه وسلم ـ كَانَ يُصَلِّي الظُّهْرَ إِذَا دَحَضَتِ الشَّمْسُ .
