“harmful”
in Edition Clear Qur'an by Talal Itani / Al-Baqara (The Cow)
2:222And they ask you about menstruation: say, “It is harmful, so keep away from women during menstruation. And do not approach them until they have become pure. Once they have become pure, approach them in the way God has directed you.” God loves the repentant, and He loves those who keep clean.”
