Reference: Sharh ‘Umdatil-Fiqh – Tape No.7, Question No.5
Question: A woman wants to perform ‘umrah, and fears the onset of her menses, so can she stipulate this when assuming the state of ihraam, thereby relieving herself of the responsibility of completing the ‘umrah when her menses begin?
Response: The onset of the menses is not something which can be stipulated [when making the intention for hajj or ‘umrah], because it is something which is [expected, and] normal. It is not [to be considered as that which] prevents, because it is the norm with women, and occurs at regular cycles, and therefore not to be considered as that which prevents – like an illness for example, or protecting yourself from enemy attack. No, it is not [to be considered as that which] prevents; [rather], this is something which is known [and expected] of the women. So, all Praise is due to Allaah [alone], let her assume the state of ihraam for hajj or ‘umrah, and when her menses start, she abstains from performing the tawaaf until she [completes her menses and] purifies herself. This is what the Prophet (sal-Allaahu ‘alayhi wa sallam) legislated when he said [to ‘Aa.ishah (radhi-yAllaahu ‘anhaa)]:
«O Allaah, [If I am prevented by an obstacle then indeed] my place is where You prevent me.»
