Translation: He proceeds to his right toward the side of the door, having arranged his upper wrap in idtiba beforehand, and circles the Kaaba seven times.
Iḍṭibāʿ is the male pilgrim's arrangement of the upper wrap, leaving the right shoulder exposed during the relevant tawaf; it is not a rule to expose that shoulder throughout every moment of iḥrām.
Shawṭ is one complete round; ashwāṭ is its plural. Each round begins and ends at alignment with the Black Stone.
