Chapter 16: The Book of Pilgrimage
Ibn Abbas (Allah be pleased with them) reported that Allah' s Apostle (ﷺ) made al-Fadl sit behind him (on the camel back) from the place (where the two prayers) are combined (Muzdalifa). Ibn Abbas (Allah be pleased with them) also informed that Allah' s Apostle (ﷺ) did not stop pronouncing Talbiya till he threw pebbles at Jamrat al-' Aqaba.
