باب التَّعْرِيسِ بِذِي الْحُلَيْفَةِ وَالصَّلاَةِ بِهَا إِذَا صَدَرَ مِنَ الْحَجِّ أَوِ الْعُمْرَةِ ‏‏
Sahih Muslim 1257 e

Nafi' reported that when 'Abdullah b. 'Umar returned from Hajj or 'Umra he made his camel kneel down (i. e. halted) in the stony ground of Dhu'l-Hulaifa where Allah's Messenger (ﷺ) had made his camel halt.

وَحَدَّثَنَا مُحَمَّدُ بْنُ إِسْحَاقَ الْمُسَيَّبِيُّ، حَدَّثَنِي أَنَسٌ، - يَعْنِي أَبَا ضَمْرَةَ - عَنْ مُوسَى، بْنِ عُقْبَةَ عَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ إِذَا صَدَرَ مِنَ الْحَجِّ أَوِ الْعُمْرَةِ أَنَاخَ بِالْبَطْحَاءِ الَّتِي بِذِي الْحُلَيْفَةِ الَّتِي كَانَ يُنِيخُ بِهَا رَسُولُ اللَّهِ صلى الله عليه وسلم ‏.‏
