It is narrated from Sayyida Aisha Siddiqa (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) performed Hajj Ifrad.
Hadith Referenceسنن دارمي / من كتاب المناسك / 1850
There are three types of Hajj: Ifrad, Qiran, and Tamattu‘.
In the aforementioned hadith, it is stated that the Messenger of Allah (sallallahu alayhi wa sallam) performed Hajj Mufrad (Ifrad), and Hajj Mufrad (Ifrad) is that the pilgrim, from the miqat, makes the intention solely for Hajj and says: “Labbayk Hajjatan,” and after performing the tawaf and sa‘i, remains in the state of ihram until he completes the stoning (rami) and shaving (halq). For the pilgrim performing Ifrad, offering a sacrifice (qurbani) is not obligatory, and this is one valid type of Hajj.
And here, by “Ifrad” is meant Hajj Qiran, because it is well-known that the Noble Prophet (sallallahu alayhi wa sallam) performed Hajj only once after the migration, as has already been mentioned in Hadith (1824), and that was Hajj Qiran, as will be mentioned ahead in (1888).
