Hajj is one of the pillars of Islam, and it is an act of worship for those who can find a way to it. The Prophet (may Allah's peace and blessings be upon him) taught us its pillars, Sunnahs, and etiquettes. In this Hadīth, the noble Companion Jābir ibn ‘Abdullāh says that the Prophet (may Allah's peace and blessings be upon him), in his Hajj, did not perform Tawāf between Safa and Marwah, except for one Tawāf, neither did his Companions (may Allah be pleased with them). Another version adds: "his first Tawāf". Tawāf here refers to Sa‘i between the mount of Safa and Marwah, which is one of the pillars of Hajj and ‘Umrah. It consists of seven rounds, the first of which starts from Safa and ends at Marwah, and the second round starts from Marwah and ends at Safa, and so on. Those of his Companions who performed Qirān Hajj - combining Hajj and ‘Umrah with one Ihrām - did not perform Sa‘i between Safa and Marwah except for once, because one Tawāf and one Sa‘i is sufficient for the performer of Qirān Hajj, as the rituals of ‘Umrah are incorporated into the rituals of Hajj. As for those who performed Tamattu‘ Hajj - assuming Ihrām for ‘Umrah in the months of Hajj and then ending its Ihrām and assuming Ihrām for Hajj - they performed two Sa‘is: one Sa‘i for their ‘Umrah and another Sa‘i for their Hajj on the Day of Nahr. This is demonstrated by a Hadīth narrated by Al-Bukhāri and Muslim, in which ‘Ā’ishah (may Allah be pleased with her) said: "Those who proclaimed Talbiyah for ‘Umrah performed Tawāf around the House and between Safa and Marwah. Then, they ended Ihrām, and then they performed another Tawāf after returning from Mina," i.e., those who performed Tamattu‘ Hajj. "As for those who combined Hajj and ‘Umrah, they performed one Tawāf," i.e., those who performed Qirān Hajj..
