Al-Kāfi - The Book of Haj

Chapter: Throwing Pebbles During the Bright Days (11, 12 and 13 of Dhu al-Hajjah) ، عن أبيه، عن ابن أبي ع٠ر بن اذينة، عن زرارة، عن أبي جعفرعليه السلا٠س، فقال أبوجعفر عليه السلا٠ا كانا رجلين فقال أحده٠ا لصاحبه: احفظ علينا ٠تاعنا حتى أرجع أكان يفوته الر٠5.

Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ‘ibn ‘Udhaynah from Zurarah who has said the following: “Abu Ja‘far (a.s.), once asked al-Hakam ibn ‘Utaybah, ‘What is the time for throwing pebbles?’ He (Hakam) replied, ‘It is at Zawal (declining of the sun toward the west at noontime).’ Abu Ja‘far (a.s.), then said, ‘Consider if they were two people and one of them said, ‘You stay guard for our luggage until I come back after throwing pebbles.

Would this not cause him to lose the time of throwing pebbles? It (the time for throwing pebbles) by Allah, is from sunrise to sunset.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (8/148))
