ثُمَّ يَأْتِي مَكَّةَ مِنْ يَوْمِهِ ذَلِكَ أَوْ مِنَ الْغَدِ أَوْ مِنْ بَعْدِ الْغَدِ.
Translation: Then he comes to Makkah that same day, or the next, or the day after that.
The sequence marker thumma moves from Mina to Makkah. The three expressions refer to 10, 11, and 12 Dhu al-Hijjah in the ordinary calendar of Hajj. Min yawmihi dhālika means on that same Day of Sacrifice.
These are the days of the text's preferred, time-bound performance. If a legally relevant excuse intervenes, detailed rules apply; delaying the tawaf does not make the tawaf obligation disappear.
