And they ask you about menstruation. Say, "It is harm, so keep away from wives during menstruation. And do not approach them until they are pure. And when they have purified themselves, then come to them from where Allāh has ordained for you. Indeed, Allāh loves those who are constantly repentant and loves those who purify themselves."

They ask you about menstruation. Say: “It is an impurity. So, keep away from women during menstruation; and do not have intimacy with them until they are cleansed. But when they are cleansed, then go to them from where Allah has commanded you. Surely Allah loves those who are most repenting, and loves those who keep themselves pure.
