Rule 420...
Rule 420: If menstruation of a lady commences and her companions will not await her becoming clean, it is permissible for her to omit the performance of the Tawaaf ul-Nisa and depart with her companions and in such a case, as a matter of caution, she should appoint an agent to perform the tawaaf and recite the prayers on her behalf.
If the menstruation commences after she had performed the fourth round, it is permissible for her to omit the performance of the remainder of the tawaaf and depart with her companions. As a matter of caution, she must appoint an agent to perform the remainder of the tawaaf and recite the prayers on her behalf.
Rule 421: The rules applicable to forgetting to recite the prayers (salaat) after the Tawaaf ul-Nisa are the same as those for forgetting to say them after the tawaaf for Umrah which is mentioned under 326 above. Rule 422: Man and woman become lawful to each other after both have performed Tawaaf- ul-Nisa and recited the prayers. The prohibition on hunting remains, as a matter of caution, till the noon of the thirteenth.
Cutting of trees and grass and hunting in the Haram is forbidden anyway as already stated above. STAY IN MINA Twelfth Obligation: The twelfth obligation in Hajj is to spend the nights of the eve of the eleventh and twelfth in Mina. It is necessary to form the intention to do so in order to attain the nearness of Allah. If, on the day of Idd, the pilgrim departs to Makkah to perform the tawaaf and saee, it is obligatory on him to return to Mina to spend the night there.
He who has not refrained from hunting in the state of ihram must also spend the night of the eve of the thirteenth in Mina. As a matter of caution, so must one who has not abstained from sexual intercourse in the state of ihram. Apart from these two categories, the remaining pilgrims can depart from Mina after Zuhr on the twelfth but if they delay their departure till night falls, they must spend the night of the eve of the thirteenth in Mina till dawn.
Rule 423: If a pilgrim prepares himself to depart from Mina and leaves the premises he occupied there but is unable to depart from Mina because of the great rush of pilgrims or for other reason, then, if it is possible for him to spend the night there, it is obligatory to do so but if there is some difficulty about spending the night there, he is permitted to leave Mina though, as a matter of caution, must sacrifice a sheep as a penalty.
