If you were to ponder you would realise that the reward for good (i.e you obeying your husband) is nothing but good (i.e, he will in return treat you good). So your obedience towards your husband leads to him being obedient to you in those things that you seek from him, because indeed a pure soul is accustomed to responding to good with good…
So it is incumbent upon you to obey your husband in al-ma’roof. And that which is apparent from the meaning of obedience is to act upon a command and to abstain from a prohibition. You should become as close to him as possible, by seeking to satisfy his wants and needs at all times.
Don’t wait for him to give you a command or to prohibit you from something.
Rather reflect on your days spent with him and on the things he loves and hates, and be quick to carry these things out. Let your actions precede his command and prohibition. For indeed this is a sign of your cleverness and dignity that you hasten towards good before he even commands it of you.
In addition to that, this obedience is something you have to be committed to and firm upon at all times. So if he were to command you with one thing or prohibit you from another thing, then do not wait for him to command you with the same thing each and every time. It is looked down upon by men of intellect that a man has to constantly reprimand his wife saying, do this and don’t do that.
If you know from your husband’s personality that he likes or dislikes a thing, don’t wait for him to command you and prohibit you, because this is from the things that lead to a husband becoming bored with his wife.
