What is the ruling on the behavior of a husband who does not work, does not fulfill his family responsibilities, stays up late on the computer, sleeps all day, and abuses his wife and children?

The wife must be patient, pray for her husband, and strive to reform him. He is responsible for his family and accountable before Allah for his guardianship. His neglect of his family and drug use expose him to Allah's wrath and severe punishment. There are indeed religious texts that warn against neglecting responsibility, abandoning prayer, and forsaking one's family. He should be advised, and if he persists in abandoning prayer, she must abstain from him until he repents.
