Hajj type
Zhra
Tamattu` means performing `Umrah during the Hajj season, and on the Day
of Tarwiah a pilgrim gets into the state of Ihram for Hajj. Anyone
intending to perform a Tamattu`` Hajj should on approaching the Miqat
make intention for `Umrah. After fulfilling the Hajj rituals, one
should offer a sacrificial animal.
Qiran Hajj
In this type of Hajj, a pilgrim should declare his intention to perform
both Hajj and `Umrah together. Only when he throws the Jamrah of
Al-`Aqabah, gets his hair shaved or cut that he can put off his Ihram.
However, he should offer a sacrificial animal.
Ifrad Hajj
In the Miqat, a pilgrim of Ifrad Hajj declares his intention for Hajj
only. He maintains his Ihram up to the Day of Sacrifice. No offering is
required from him.
Umrah
Rituals of `Umrah
In Arabic the word `Umrah is derived from I`timar which means a visit.
However, `Umrah technically means paying a visit to Ka`bah, performing
Tawaf [Circumambulation] around it, walking between Safa and Marwah
seven times. A performer of `Umrah puts off his Ihram by having his
hair shaved or cut.
