Sulaiman bin Amr bin Ahwas's mother, Umm Jandab (may Allah be pleased with her), says: I saw the Prophet Muhammad (peace and blessings be upon him) on the Day of Sacrifice at Jamrah Aqabah. He went down into the valley, and he threw seven pebbles at Jamrah Aqabah, saying "Allahu Akbar" with each pebble, then he returned. Through this chain as well, (from Sulaiman bin Amr bin Ahwas's mother, Umm Jandab, may Allah be pleased with her), a similar hadith has been narrated.
