When is it obligatory to pray for the one who has become pure from menstruation?

Question:
She became pure from menstruation one hour after the 'Asr prayer. Should I pray the Dhuhr and 'Asr?

Answer:
Yes, yes. If a woman becomes pure from her menstruation or post-natal bleeding during the 'Asr time, she prays the Dhuhr and 'Asr, because she is among those with an excuse who prays both. Likewise, if she becomes pure at night, she prays the Maghrib and 'Isha. A group of the Companions of the Prophet (peace and blessings be upon him) issued a fatwa to this effect, and it is a clear matter. It is like the sick person who prays the combined prayer with delay: if he feels energetic during the 'Asr time, he prays with the Dhuhr, and it is permissible for him to delay the Dhuhr with the 'Asr. Likewise, if he delays it once with the 'Isha, it is the fulfillment of the sick person and the traveler. It is most similar to the sick person in that she is excused by a matter that is not apparent to him.
