(Al-Hajj) 22 : 29
ثُمَّ لْيَقْضُوا تَفَثَهُمْ وَلْيُوفُوا نُذُورَهُمْ وَلْيَطَّوَّفُوا بِالْبَيْتِ الْعَتِيقِ
Then let them fulfill their prescribed duties and fulfill their vows and perform circumambulation around the ancient House".
Prescribed duties mean haircutting, nail cutting, bathing, etc. It also means one should change the pilgrimage dress to good ones. Then the pilgrims of Hajj should circumambulate Ka’bah and run between Safa-Marva. See explanation 3: 96-97.
