Musannaf Ibn Abi Shaybah

Ibrahim says that there is no (obligation of) sacrifice (dam) in the stoning of the Jamarat except for Jamrah Aqabah; that is, if someone stoned any other Jamrah before it, which should have been stoned after it (then sacrifice becomes obligatory).

Hasan says regarding the person who performs the stoning at the second Jamrah before the (correct) Jamrah (i.e., leaves the one he was supposed to do and does another instead), then there is nothing upon him.
