What are the pillars and obligations of Hajj, in order, for the three types of Hajj (Tamattu‘, Ifrad, and Qiran), and do they differ from one another?

There are three types of rituals for Ihram:

1. Tamattu': Entering into Ihram for Umrah during the months of Hajj, completing it, and then performing Tahlul (release from Ihram). Then, entering into Ihram for Hajj on the 8th of Dhul-Hijjah. One bathes, applies perfume, and puts on the Ihram garments at the Miqat, saying: "Labbaik Umrah" (Here I am, O Allah, for Umrah). One performs Tawaf and Sa'i, shortens the hair, and completely exits from Ihram. Then, on the 8th of Dhul-Hijjah, one enters into Ihram for Hajj from their location. A Tamattu' pilgrim is required to offer a Hady (sacrifice).

2. Ifrad: Entering into Ihram for Hajj only. At the Miqat, one says: "Labbaik Hajjan" (Here I am, O Allah, for Hajj). One performs Tawaf Al-Qudum (Tawaf of Arrival) and Sa'i for Hajj, and remains in Ihram until the Day of Eid. There is no Hady required for an Ifrad pilgrim.

3. Qiran: Entering into Ihram for both Umrah and Hajj together. At the Miqat, one says: "Labbaik Umratan wa Hajjan" (Here I am, O Allah, for Umrah and Hajj). One performs Tawaf Al-Qudum and Sa'i for both Umrah and Hajj, and remains in Ihram until the Day of Eid. A Qiran pilgrim is required to offer a Hady.

The Hady is a sheep, or one-seventh of a camel, or one-seventh of a cow, to be slaughtered during the days of sacrifice. If one cannot find an animal, they fast three days during Hajj and seven days when they return to their family. The best of these rituals is Tamattu', except for one who has brought the sacrificial animal from the Miqat, in which case Qiran is better.
