Hajj is one of the five pillars or central duties of Islam.
It is a set of acts of worship to be performed in and around Mecca (Makkah) at least once in a lifetime by every Muslim satisfying certain conditions.
The Hajj pilgrim coming from a place distant from Mecca, assumes the ihram from the miqat on their way, or from a point parallel to the closest miqat, and starts reciting the talbiyah. In this there is no difference between one performing `Umrah mufradah or any of the three types of Hajj (i.e.tamattu, ifrad, qiran). However, those who live within the haram of Mecca assume ihram from their houses.’
