The Qur’an teaches that men are superior to women and should beat those from whom they “fear disobedience”: “Men have authority over women because Allah has made the one superior to the other, and because they spend their wealth to maintain them. Good women are obedient. They guard their unseen parts because Allah has guarded them. As for those from whom you fear disobedience, admonish them and send them to beds apart and beat them.” — Qur’an 4:34
Muhammad’s child bride, Aisha, says in a hadith that Muhammad “struck me on the chest which caused me pain, and then said: ‘Did you think that Allah and His Apostle would deal unjustly with you?’” — Sahih Muslim 2127
The Qur’an likens a woman to a field (tilth), to be used by a man as he wills: “Your women are a tilth for you, so go to your tilth as you will” — Qur’an 2:223
