It is, though, obligatory to clean oneself for the prayer after tawaf.

It is, though, obligatory to clean oneself for the prayer after tawaf. Rule 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.

Rule 289: When the periods of Haydh and Nifas are over, and for one in Janabah, ghusl is obligatory for the performance of tawaf. If it is not possible to do so, and there is no hope of any possibility of performing ghusl, tawaf must be carried out with tayammum. In such a case, as a matter of recommended precaution, an agent must also be appointed to perform the tawaf;if even tayammum is not possible, the appointment of the deputy is called for.

Rule 290: If in the course of Umrat-ut-Tamatu, a lady, whether in a stateof ihram or not, starts her monthly period;there may not be sufficient time for performingUmrah. She should wait for the period to be over, perform ghusl and Umrah. If, however, the time is short, two possibilities could arise: if the period commenced before assuming ihram, she should change to Hajj-ul-Ifrad; on completing Hajj rituals, it is obligatory on her to perform Umrat-ul-Mufradah, where possible.

if the period commences after wearingihram, she is free to either performHajj-ul-Ifraad, as outlined in the preceding paragraph, or perform the ceremonies of Umrat-ut-Tamatu, without performing tawaf and its prayer. After sa'y, she should perform taqseer, andthen wear ihram for Hajj. On returning to Makkah, after completing the rituals at Mina, she should performtawaf of Umrah, before performing tawaf for the Hajj.

If even then the bleeding continued and, she was convinced, that it will continue until after the return from Mina, she should hire an agent to perform the tawaf for her. She should perform the sa'y herself.

Rule 291: If the bleeding commences when a lady, in a state of ihram, is in the course of tawaf, and if it occurs before completing the fourth round, the tawaf is invalid, and the rule in this case is as stated above.If, however,it occurs after the fourth round, what was performed is valid;it is obligatory, though, to complete the remainder of the tawaf after ghusl.
