RULES FOR UMRAH

Umrah is Sunnat Mu'akidah: Umrah is neither imperative (Fard) nor obligatory (wajib), but performing Umrah once in a life time is Sunnat Mu'akidah. However, once or more than once, whenever it is performed, it fetches great rewards.
No Fixed Time: There is no fixed month, day or time for Umrah as it is for Hajj. As said earlier, it can be performed any time one desires.
The Miqat for Umarh: The station of Ihram (Miqat) for Umrah is Hill for the residents of the Haram of Mecca and the people of Hill. As mentioned later, the area between the five appointed Miqats of Hajj and the bounds of the Haram of Mecca is called Hill. The Afaqis (outsiders) who come to Mecca for Hajj and Umrah should already be in Ihram before entering into Mecca. However, for subsequent Umrahs, even they have to go to Hill to put on Ihram. For this purpose, buses outside Bab Abdul Aziz of al-Haram take pilgrims to Masjid Aai'sha which is in Hill on Madinah Road at Tan'eem, not far from Mecca.
The Rites of Umrah: The only rites of Umrah are:
Entering the state of Ihram
Tawaf of Ka'bah
Sa'yee between the hills of Safa and Marwah
Shaving or clipping of the hair
