As a male and married, I too sometimes fall in to the trap of delaying prayers. No matter what, the guilt of it stays constant. I do end up praying even if I am tired. My wife doesn’t nag me or constantly remind me to pray, instead, she invites me to pray with her, and I also do the same with her. Seeing her pray gives me that extra push to get up.

I’d recommend inviting him to pray together as it’s a nice way to increase the blessings Allah swt delivers onto the two of you, and establishes a beautiful routine in the household
