Mishkat al-Masabih 10 The Rites of Pilgrimage كتاب المناسك 40

وَعَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: تَمَتَّعَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي حَجَّةِ الْوَدَاعِ بِالْعُمْرَةِ إِلَى الْحَجِّ بدأَ فأهلَّ بالعمْرةِ ثمَّ أهلَّ بالحجّ

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.
