Sahih al-Bukhari, Book 64, Hadith 176 (In-Book) ⓘ
Narrated Ibn `Umar: I took part in a Ghazwa towards Najd along with Allah's Messenger and we clashed with the enemy, and we lined up for them.
حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سَالِمٌ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ غَزَوْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم قِبَلَ نَجْدٍ، فَوَازَيْنَا الْعَدُوَّ فَصَافَفْنَا لَهُمْ.
