عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: كُنْتُ أُطَيِّبُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لِإِحْرَامِهِ قَبْلَ أَنْ يُحْرِمَ وَلِحِلِّهِ قَبْلَ أَنْ يَطُوفَ بِالْبَيْتِ بِطِيبٍ فِيهِ مِسْكٌ كَأَنِّي أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفَارِقِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ مُحْرِمٌ

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.
