Sayyiduna Fadl bin Abbas (may Allah be pleased with them both) narrates that I was riding behind the Prophet (peace and blessings of Allah be upon him), and he continued to recite the Talbiyah until he stoned Jamrah Aqabah. He threw seven pebbles at it, and with each pebble he said « اللهُ أَكْبَرُ ». Imam Abu Bakr (may Allah have mercy on him) says that the narration of Umar bin Hafs Shaybani from Hafs bin Ghiyath pertains to another chapter.
