Hajj & Umrah

Hajj refers to tying the Ehraam (i.e. Entering into the state of Ehraam) and staying at 'Arafaat on the 9th of Zil-Hijjah, and the performing of Tawaaf; and a fixed time has been stipulated for this, so if these actions are done within this fixed time, it is Hajj.

Hajj became Fard in (the year) 9 Hijri, and it being Fard is Qata'ee (i.e. Absolute and explicit). One who rejects it (i.e. Does not believe in it) being a Fard, is a Kaafir (i.e. He is an unbeliever). However, it (Hajj) is only Fard once in a lifetime. [Alamgiri, Durr e Mukhtar]
