Abd al-Rahman bin Abdullah bin Umar (may Allah be pleased with them) narrated this hadith from his father and his uncle, but he did not mention "the three days", and the narration of al-Ashyab also does not explicitly state the three.
Imam al-Shafi'i (may Allah have mercy on him) said: Since he stoned riding on the day of sacrifice because his riding continued on from Muzdalifah, it would be analogous that he stoned riding on the day of departure because his riding continued into his departure. The Shaykh said: This is also the view of Ata bin Abi Rabah (may Allah have mercy on him).
