It was narrated from Jabir bin ‘Abdullah, Ibn ‘Umar and Ibn ‘Abbas that when the Messenger of Allah (ﷺ) and his Companions came (to Makkah) to perform their Hajj and ‘Umrah, they only performed Tawaf once.
It was narrated from Jabir that the Prophet (ﷺ) performed one Tawaf for Hajj and ‘Umrah.
It was narrated from Ibn ‘Umar that he came (to Makkah) to perform Hajj and ‘Umrah together (Qiran). He circumambulated the House seven times, and performed Sa’y between Safa and Marwah, then he said: “This is what the Messenger of Allah (ﷺ) did.”
It was narrated from Ibn ‘Umar that the Messenger of Allah (ﷺ) said: “Whoever enters Ihram for Hajj and ‘Umrah, one Tawaf is sufficient for both, and he should not exit Ihram until he has completed his Hajj, when he should exit Ihram for both.”
