al-Qasim ibn Muhammad القاسم بن محمد بن أبي بكر الصديق · The Book on Hajj

"The Prophet started the Talbiyah after the Salat."

"When Abdullah went to stone Jamrat Al-Aqabah, he went to the middle of the valley, faced the Ka'bah, and proceeded to stone the Jamrah at its southern wall. Then he stoned with seven pebbles, saying: "Allahu Akbar" with each pebble. Then he said: 'By Allah except Whom none is worthy of worship. This is where the one stoned to whom Surat Al-Baqarah was revealed.'"

"The Prophet purchased his Hadi in Qudaid."

"A man asked the Messenger of Allah: 'I shaved before slaughtering.' So he said: 'Slaughter, and there is no harm.' Another man asked him: 'I performed the sacrifice before stoning.' He said: 'Stone, and there is no harm.'"

His father disliked making a condition during Hajj and he said: 'Is not the Sunnah of your Prophet enough for you?"
