Cleanliness 24 Because she is not taahir...
Cleanliness 24 Because she is not taahir, she may not perform the tawaaf and its prayer, as it is normally required. It is conditional in tawaaf, that one is clean and taahir from faeces and urine, if the tawaaf is an obligatory one. If the tawaaf was mostahab, tahaarah from urine is not conditional. It is forbidden for one who is not taahir from faeces to enter Masgid al-Haraam – the Grand Mosque – and tawaaf can only be done in the Masgid al-Haraam, around the sacred Ka‘bah.
One who is not able to achieve tahaarah by washing with water, due to an illness and such likes, tahaarah by earth – tayammum – can replace the tahaarah by water. Thus, if one, due to a reason, could not wash after excretion, he must perform tayammum instead. With the exception of Janaabah, he is also required to perform wudhu if he could do the wudhu, otherwise he would need to do another tayammum instead of the wudhu, and then perform the tawaaf.
In the case of a woman experiencing Istihaadha – undue or lesser menses [this is compared with the normal monthly menses referred to as Haydh], if it is not possible for her to achieve tahaarah by washing with water, then it is sufficient for her to perform the emergency tahaarah – i.e. the tayammum – and by doing so her tawaaf is valid.
Similarly, the same ruling applies to other cases such as those with difficulties in controlling their bowel/wind movement or urine, although it is a priority precaution to do the tawaaf himself, and then hire an agent to do so on his behalf. If one performed the tawaaf, and afterwards remembered that he did not have tahaarah, if the tawaaf was obligatory, it is mandatory for him to seek tahaarah and repeat the tawaaf again. If in the course of the tawaaf, one passes wind, urine, etc.
[which annuls the wudhu, and any such occurrence is referred to as hadath] if he had not exceeded half of the tawaaf, then he must seek tahaarah [and/or wudhu] and repeat the tawaaf again from the beginning. If on the other hand, this occurred when he had exceeded half of the tawaaf, then he must seek tahaarah [and/or wudhu] and complete the tawaaf from where the hadath occurred. In this case, both the first and this latter part of tawaaf are valid.
If one had doubt between being in a state of tahaarah and the occurrence of hadath, regardless of whether this [doubt] was before, after or during the tawaaf, the same ruling applies as that of the daily obligatory prayers.
