Reciting Talbiya when one has mounted his mount and it stood up straight (ready to set out)

Sahih al-Bukhari · Book 25 · Hadith 1552

حَدَّثَنَا أَبُو عَاصِمٍ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، قَالَ أَخْبَرَنِي صَالِحُ بْنُ كَيْسَانَ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ أَهَلَّ النَّبِيُّ صلى الله عليه وسلم حِينَ اسْتَوَتْ بِهِ رَاحِلَتُهُ قَائِمَةً‏.‏

Narrated Ibn `Umar: The Prophet (p.b.u.h) recited Talbiya when he had mounted his Mount and was ready to set out.
