Sahih al-Bukhari 1514
Sahih al-Bukhari · Book 25: Hajj (Pilgrimage) · The Statement of Allah Most High: "Call ˹all˺ people to the pilgrimage.1 They will come to you on foot and on every lean camel from every distant path, so they may obtain the benefits ˹in store˺ for them, ..."
Narrated Ibn `Umar:
حَدَّثَنَا أَحْمَدُ بْنُ عِيسَى ، حَدَّثَنَا ابْنُ وَهْبٍ ، عَنْ يُونُسَ ، عَنِ ابْنِ شِهَابٍ ، أَنَّ سَالِمَ بْنَ عَبْدِ اللَّهِ، أَخْبَرَهُ أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَرْكَبُ رَاحِلَتَهُ بِذِي الْحُلَيْفَةِ ثُمَّ يُهِلُّ حَتَّى تَسْتَوِيَ بِهِ قَائِمَةً.
I saw that Allah's Messenger (ﷺ) used to ride on his Mount at Dhul Hulaifa and used to start saying, "Labbaik" when the Mount stood upright.
