Imam Ibrahim, may Allah have mercy on him, said: Four (persons) will not recite the Qur'an: the one who is in the toilet, the one who is in the bathhouse, the one who is in a state of major ritual impurity (janabah), and the menstruating woman. However, the menstruating woman and the one in a state of janabah may recite a verse or a sentence.
