Our Wives hold the most powerful part of every marriage, so treat them with respect.
If you want your children to practice Islam easily, then focus on their mother, your wife. Mothers plays greater role in restoring Deen in the home, similar to how they play greater role in destroying Deen in the home. If the Deen of your wife is intact, then be rest assured your children are in a safer hand, and if the Deen of your wife is a modernized Deen, then be rest assured of a tainted Deen in the home.
You find out today, most husbands pay less/no attention in maintaining the Deen of their wives. They think Islam is just, 'my wife is wearing hijab'. We don't nurture our wives, we don't teach/are not serious in teaching them Islam. We just concern about wearing same suit materials, going out for Islamic programs, taking selfies posting here and there, wedding anniversaries, for people to know we are really having a good time as couples.
How many men today you see are somehow knowledgeable and very careless in impacting that knowledge in their wives?! In the Qur'an Allāh says: "O you who have believed, protect yourselves, and your families from fire whose fuel is people and stones"..... (Quran 66 ayah 6)
It has to be the responsibility of the husband to know the daily routine of the wife at home. The children are following the ideology, and the life style of the woman at home. husband and wife is not just about 'bedroom game'. It has to be a commitment where the both of you should strive in attaining the mercy of Allah.
The hard core fact here is, if you don't pay attention to the DEEN of your wife, her Worships and learning, then surely your children are going to grow up with twisted mentalities, and you will end up messing your own Deen because Allah is going to hold you to account for that.
It is not love if you're really not paving a way for attaining Allah's mercy in the home. Don't just entertain your wife, nurture her too for the benefit of the kids.
May Allah grant us spouses that are there to help us in attaining the mercy of Allah Aameen.
