سنن ابن ماجه

It was narrated that ‘Abdur-Rahman bin Yazid said: “When ‘Abdullah bin Mas’ud stoned ‘Aqabah Pillar, he went to the bottom of the valley and turned to face the Ka’bah, with the Pillar on his right hand side. Then he threw seven pebbles, saying the Takbir with each one. Then he said: ‘From here, by the One besides Whom there is none worthy of worship, did the one throw, to whom Surat Al-Baqarah was revealed.’”
