'Adullah bin 'Amr (b. al-'As) (RA) reported that a person came to Allah's Apostle (ﷺ) and said: I got (my head) shaved before sacrificing the animal, whereupon be (the Holy Prophet) said: Sacrifice the animal (now); there is no harm in it. He (the person said): I sacrificed the animal before throwing pebbles, whereupon he said: Throw pebbles (now); there is no harm in it.
