فَإِذَا دَخَلَ مَكَّةَ ابْتَدَأَ فَطَافَ بِالْبَيْتِ سَبْعَةَ أَشْوَاطٍ
Translation: When he enters Makkah, he begins by circumambulating the House for seven circuits.
In this sequence the first set of seven circuits is the Umrah tawaf, even though the ihram is shared between both rites. The phrase sabʿata ashwat specifies seven complete circuits. It should not be merged conceptually into a later seven-circuit tawaf for Hajj.
