I was riding behind the Prophet ﷺ, and I kept hearing him recite the talbiyah until he threw the pebbles at Jamrat al-Aqaba. When he threw them, he stopped the talbiyah.
حدثنا هناد بن السري حدثنا أبو الأحوص عن خصيف عن مجاهد عن ابن عباس قال
كنت ردف النبي ﷺ فما زلت أسمعه يلبي حتى رمى جمرة العقبة فلما رماها قطع التلبية
[Sahih] Narrated by Nasai, in the Rites of Hajj, chapter of "the muhrim cuts off the talbiyah when he throws at Jamra Uqba," hadith no. 3082, from Hannad, through Khaseef, as mentioned earlier at hadith no. 1173. He was not the only one to narrate it, for Saeed bin Jubayr also narrated it from Ibn Abbas from Fadl with the same wording, and Nasai recorded it at hadith no. 3084. Its chain of transmission is sahih, and it has corroborating narrations.
