There are three types of Hajj, a) Hajj-e-Ifrad b) Hajj-e-Qiran c) Hajj-e-Tamattu
Hajj-e- Ifrad: The person who performs Hajj-e-Ifrad is called a Mufrid. Before passing through Miqaat (the place for assuming Ihraam) one will enter in the state of Ihraam and with the Niyyah of performing Hajj alone. A Mufrid does not combine Umrah with their Hajj. Hajj-e-Ifrad is the only kind of Hajj allowed for the residents of Makkah and the Hills (those who reside between Miqaat and the precincts of Haraam) for example Jeddah.
Hajj-e-Qiran: Literally Qiran means to combine two things. A pilgrim who performs this kind of Hajj combines Hajj and Umrah. After performing Umrah a Qarin (person who is performing Hajj-e-Qiran) will perform Hajj with that same Ihraam.
Hajj-e-Tamattu: Tamattu literally means to enjoy or take advantage of a facility. A pilgrim who performs Hajj-e-Tamattu combines both Umrah and Hajj. The difference between Hajj-e-Qiran and Hajj-e-Tamattu is that after performing Umrah the Mutamatti (person who performs Hajj-e-Tamattu) relinquishes his/her Ihraam and on the 8th of Dhul Hijjah he/she resumes that Ihraam.
