The questioner says:

"My husband has memorised the Qur’an and studied some Islamic knowledge. When he’s outside the house, he treats people kindly and has good manners. But at home, he’s the opposite—he has no good character, doesn’t speak kindly, doesn’t smile, and he hits me. He spends more time outside than at home. When I try to talk about it, he says, ‘I don’t want to hear anything from you—every household has its secrets.’” Excellent answer by Sheikh Abdulhameed Az-Zu'kari hafidahullāh
