Ibn ‘Umar said that at the Farewell Pilgrimage God’s messenger performed the ‘umra first and the hajj later (The phrase used is tamata'a bil-’umra ilal-hajj which indicates gaining the advantage of the ‘umra and waiting till the time for the hajj comes without requiring to wear the ihram during the intervening period. It is a difficult phrase to translate, and therefore one can only indicate its general meaning in a translation), raising his voice in the talbiya first for the 'umra and afterwards for the hajj.
We went out with God’s messenger in the year of the Farewell Pilgrimage, some of us raising our voices in the i>talbiya for an ‘umra, some for hajj and ‘umra, and others for the hajj, but God’s messenger raised his voice in the talbiya for the hajj. Those who did it for an 'umra took off the ihram, but those who did it for the hajj, or who combined the hajj and the ‘umra did not remove the ihram till the day of sacrifice.
