Mishkat al-Masabih

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. Bukhari and Muslim.
