“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.’”
Sunan Ibn Majah Book 25, Hadith 149
