We know it is discouraged – makruh – for a woman to recite more than seven ayat of
Qur’an during her menstrual period – haidh. On the other hand, it is highly recommended to read Qur’an in the Holy month of Ramadan.
How should a woman get this reward – thawab? Should she, during the month of Ramadan, recite more than seven ayat of Qur’an while she has her menstrual period?

As a general rule it is highly recommended to recite Qur’an and nourish the soul with the
remembrance of Allah – dhikr Allah. However, there are exceptions to every rule. During their monthly menstrual periods the reward women get from reciting Qur’an is less than when they are not in this condition. They can recite more than seven ayat. This is based on a hadith reported in Shi’ah resources which elucidate Shari’ah – Wasa’il al Shi’ah – compiled by the Shi’ah scholar al Hurr al-Amili, Vol. 2, p. 218, edition published in Qum in 1409 AH.
The author however says that the other four schools of thought are very strict about this issue. When the word makruh is applied to worship – ibadat – it carries the implication of a lesser reward, rather than any connotation that something is reprehensible or blameworthy.
