Is a wife considered among a man's written provisions (rizq)?

Sustenance (rizq) is everything that Allah provides for His servant from which he benefits. This includes a wife and other things. As-Saffarini defined sustenance as that which is beneficial, whether lawful or its opposite. Allah decreed the destinies of creatures fifty thousand years before He created the heavens and the earth, and no one can benefit or harm you except with what Allah has ordained for you or against you.
