What is advice for a lazy, selfish husband without nagging?

So there are two aspects for this. Number one, there's a specific du'a in Sahih Bukhari the Prophet sallallahu alayhi wa sallam mentioned for laziness: اللهم إني أعوذ بك من الهم والحزن والعجز والكسل. So have a look at that du'a. Number two, as you mentioned, you don't want your husband to feel like he's being nagged. What that does is when he feels he's constantly under bombardment, he's constantly being nagged, that for the male psyche, it then breeds resentment that not only does he not want to do it, he really is driving the other way in terms of he's adamant now that he definitely doesn't want to do it. So what you want to do is try and empower him. That's the way that husbands will respond, that males will respond. And a common example I give is that often I get the question, maybe my husband doesn't always pray as much as I would like them to or as much as me. So one thing you can do in this scenario is that if you empower your husband, and this is the key aspect, try and empower them rather than feel it as though they feel anyway that they have been having a go at. So you say to your husband, look, I love it when you lead me. I really enjoy it when you lead me. Please, can you lead me and we can pray together? And that will really empower him.
