Tawaf is one of the essential pillars of ‘Umrah. The Tawaf of `Umrah is seven circuits, starting and ending at the Black Stone, because the Prophet (peace and blessings be upon him) performed Tawaf in this manner. He said: “Learn from me your rituals (of pilgrimage).”
If a pilgrim who is performing Hajj Tamattu` did not complete the Tawaf of `Umrah, his Hajj is no longer Hajj Tamattu`. The correct name for it is Hajj Qiran as his `Umrah is incomplete. The pilgrim removed his ihram attire and had intercourse with is wife because he thought he had finished his `Umrah, therefore, he does not have to offer any expiation.
In this regard, the late Sheikh Ibn `Uthaymeen, a prominent Saudi Muslim scholar, (may Allah shower mercy on his soul), issued the following:
“In effect, anyone that falls under this category has performed Hajj Qiran as they joined Hajj with `Umrah before Tawaf, because their first Tawaf was not complete. Joining Hajj to `Umrah means that one is doing Hajj Qiran.
