Sukainah the daughter of Shaikh al-Albaani said, “I asked my father, may Allaah have mercy on him, ‘How does the female who has the excuse accorded to her by the Sharee’ah [i.e., menses] perform worship on the Night of Decree?’
So He answered me, saying, ‘By supplicating, remembering Allaah [dhikr] and reciting the Quraan, and there is no problem in her doing that. And I think that you are sure about the fact that it is not disliked for the menstruating woman to recite the Quraan. So this is the way out from one angle.
And from another, it is fitting for the Muslim in such circumstances, whether he is male or female, to emulate the Prophet عليه السلام who said, ‘Seize the benefit of five before five: your youth before you become old, and your health before you become ill …’ [Saheeh at-Targheed wat-Tarheeb, no. 3355]. For what reason [did he say this?] Because in Sahih al-Bukhari it has been reported that, ‘When a slave [a believer] falls ill or travels, then he will get written to his accounts [the reward] similar to that which he used to get for his good deeds practised at home and in good health [as if he is doing them on his journey and in illness].’ [Bukhaari 2996]
So it is upon such a woman to seize the opportunity of benefitting from her time when she is clean and is able to stand during the last ten nights, or at least the odd nights, or at the very least the day or night of the twenty-seventh.
For indeed when Allaah, the Mighty and Majestic, knows that His female servant used to do that when she was able to stand in prayer then suddenly comes into a state where she is excused, He records for her what used to be written for her when she was in a state of purity.
This is a very important point. Its fruits are that the Muslim should strive as was just explained: that he should always spend his time in obedience as much as he is able to. Such that when his obedience increases and the worship then passes him by [due to him becoming ill or travelling, the reward] is still written for him even if he is not able to actually perform it.’
