Before the 8th of Dhul-Hijjah, a person who wants to perform pilgrimage (Hajj) pronounces the intention to perform Umrah while approaching the Miqat. A second intention for the actual Hajj is pronounced at a later period. There are several rites to properly complete the Hajj and Umrah.
The rites of Umrah and Hajj may include but are not limited to:
Putting Ihram, performing supererogatory (Sunnah) prayers, making several types of Tawaf, reciting Talbiyah, doing Saee between Safa and Marwah, trimming and/or cutting hair, praying and staying in Mina, praying and standing in Arafah, praying and staying in Muzdalifah, throwing pebbles in three Jamrahs, sacrificing an animal, praying behind Maqam Ibrahim, and drinking from the well of ZamZam.
In the case of Hajj at-Tamattu, after completing the Umrah, the pilgrim trims his/her hair, showers, and changes into everyday clothes. These steps complete the Umrah portion. All restrictions of the Ihram are temporarily lifted. The pilgrim waits until the 8th of Dhul-Hijjah to start the rites of Hajj.
On the 8th of Dhul-Hijjah, the pilgrim pronounces a new niyyah at the place to perform Hajj. There is no need to go to Miqat for this. The pilgrim changes into Ihram in the prescribed manner and proceeds to Mina soon after the Fajr Prayers.
