Ritual 288

If it is not possible to perform wudhu, for a reason not likely to change [in time], tayammum must be performed for tawaf. If even tayammum is not possible, tawaf itself cannot be performed. When all hope of possibility fades away, an agent must be appointed to perform tawaf on his behalf. However, as a matter of optionalrecommended precaution (al ahwatil awla), he must also perform tawaf without wudhu or tayammum.
