It is permissible to offer the sacrifice before stoning the Jamrah, or to shave before offering the sacrifice or stoning the Jamrah, or to perform Tawaf before any of them

'Abdullah b. 'Amr b. al-'As (Allah be pleased with them) reported: Allah's Messenger (ﷺ) stopped while riding his camel and the people began to ask him. One of the inquirers said: Messenger of Allah, I did not know that pebbles should be thrown before sacrificing the animal, and by mistake I sacrificed the animal before throwing pebbles, whereupon Allah's Messenger (ﷺ) said: (Now) throw pebbles and there is no harm in it. Then another (person) came saying: I did not know that the animal was to be sacrificed before shaving, but I got myself shaved before sacrificing the animal, whereupon he (the Holy Prophet) said: Sacrifice the animal (now) and there is no harm in it. He (the narrator) said: I did not hear that anything was asked on that day (shout a matter) which a person forgot and could not observe the sequence or anything like it either due to forgetfulness or ignorance, but Allah's Messenger (ﷺ) said (about that): Do it; there is no harm in it.
