Is the marriage contract valid if one of the spouses is in a state of ritual impurity (junub) or if the wife is menstruating? And does divorce occur if one of the spouses is in a state of ritual impurity (junub) or if the wife is menstruating?

Janabah (definition) (ritual impurity due to sexual discharge) and menstruation do not affect the validity of a marriage contract, as ritual purity is not among its pillars or conditions for its validity. As for divorcing a menstruating woman, or divorcing her during a period of purity in which he had intercourse with her, this is an innovated divorce (talaq (definition) bid'i), which is forbidden by consensus, but it is valid. The divorce pronounced by a person in a state of janabah is also valid, whether his janabah was due to his wife or not, because ritual purity from janabah is not a condition for the occurrence of divorce.
