Hajj is one of the pillars of Islam, and it is an act of worship for those who can find a way to do it. Ihrām for it can either be assumed as Ifrād, Qirān, or Tamattu‘, which is performing ‘Umrah before Hajj. This Hadīth clarifies one of the aspects of the Prophet's performance of Hajj in the Farewell Hajj. He performed Qirān Hajj, combining Hajj and ‘Umrah, because he had the sacrificial animals with him. Therefore, Jābir ibn ‘Abdullāh (may Allah be pleased with him) said: "Neither the Prophet (may Allah's peace and blessings be upon him) nor his Companions performed Tawāf between Safa and Marwah except for one Tawāf." Another version adds: "his first Tawāf," i.e., the Prophet (may Allah's peace and blessings be upon him) and those with him who performed Qirān Hajj did not engage in Sa‘i between Safa and Marwah except for one Sa‘i, which is the Sa‘i performed along with Tawāf al-Qudūm (Arrival). Indeed, one Tawāf and one Sa‘i are sufficient for the performer of Qirān Hajj, in which the rituals of ‘Umrah are included in the rituals of Hajj. As for those who perform Tamattu‘ Hajj, doing ‘Umrah before Hajj, they are required to perform two Sa‘is: one Sa‘i for their ‘Umrah and one Sa‘i for their Hajj on the Day of Nahr (Slaughter). This is clarified by a Hadīth narrated by Al-Bukhāri and Muslim, and the wording here is of Al-Bukhāri, in which ‘Ā’ishah (may Allah be pleased with her) reported: "Those who raised their voices in 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," i.e., who performed Qirān Hajj, "they performed one Tawāf.".
