I saw Ibn Masud throw the pebbles at Jamrat al-Aqaba from the bottom of the valley, then he said, "By the One besides whom there is no god, this is the standing place of the one to whom Surat al-Baqarah was revealed."
حدثنا هشيم حدثنا مغيرة عن إبراهيم حدثنا
رأيت ابن مسعود رمى الجمرة جمرة العقبة من بطن الوادي ثم قال هذا والذي لا إله غيره مقام الذي أنزلت عليه سورة البقرة
Its isnad is sahih. Hushaym is Ibn Bashir. Mughira is Ibn Miqsam Dabbi. Ibrahim is Nakhai, and he is Ibrahim bin Yazid bin Qays bin Aswad bin Amr bin Rabia bin Dhuhl. Abdul-Rahman is Nakhai, and he is the maternal uncle of Ibrahim Nakhai, and he is Abdul-Rahman bin Qays bin Abdullah bin Malik bin Alqama bin Salaman bin Kahl bin Bakr bin Awf bin Nakha, with a fatha on the kha, and he is a trustworthy successor, narrated from by the authors of the six books.
