Some essential conditions are:

• Intention (niyyah) for the sake of Allah

• Ritual purity (wudu or ghusl; for women, being free from menstruation or postpartum bleeding)

• The body and clothing must be free from impurities

• Starting from the Black Stone (Hajar al-Aswad) and ending at the same point

• Performing Tawaf within the area between the Kaaba and Maqam Ibrahim

If wudu becomes invalid during Tawaf, one must either restart or complete the Tawaf according to the number of circuits completed.
