Sayyiduna Asim bin Adi (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) granted permission to the camel herders regarding the nights of Mina that they should stone (the Jamarat) on the Day of Sacrifice (Yawm al-Nahr), then combine the stoning of the two days after sacrifice and perform them all in one day. Malik says: I think he said to do the stoning on the first day, then when returning from Mina, to stone (the Jamarat).
