From Sahih Muslim (Hadith 3160):
This hadith has been narrated on the authority of Ibn Juraij with the same chain of transmitters. And the narration of Ibn Bakr is like one transmitted by 'Isa but with this (variation):" There are not these words in it: To all these three rites (throwing of pebbles sacrificing of animal and shaving of one's head)." And so far as the narration of Yahya al-Umawi (the words are): I got (my head) shaved before I sacrificed the animal, and I sacrified the animal before throwing pebbles, and like that
