The Book of Pilgrimage (Kitab Al-Hajj)
Muslim :: Book 7 : Hadith 2665
Abu Zubair reported that he heard Jabir b. 'Abdullah (Allah be pleased with them) saying that as he was asked about (the places for entering upon the) state of ihram, he said: I heard (and he then carried the narration directly, I think to) the Apostle of Allah (may peace be upon him).
