سورة An-Nisa ( The Women ) - الآية 34

Men are in charge of women, as Allah has made one of them superior to the other, and because men spend their wealth for the women; so virtuous women are the reverent ones, guarding behind their husbands the way Allah has decreed guarding; and the women from whom you fear disobedience, (at first) advise them and (then) do not cohabit with them, and (lastly) beat them; then if they obey you, do not seek to do injustice to them; indeed Allah is Supreme, Great.
