Is the fear of Allah withholding a suitor, if it leads to increased closeness to Allah and abandoning what displeases Him, considered a correct and acceptable act, or must closeness to Allah be purely for His sake alone?

The fear that you might be deprived of marriage to a righteous man because of sin is a valid fear, because sins and transgressions remove blessings and prevent them. Allah does not change His blessing upon a people until they change what is in themselves from obedience to disobedience. Allah may afflict you by making your suitor dislike you due to your persistence in sin. Therefore, we advise you to repent to Allah from sins and transgressions, and to adhere to His commands and stay away from His prohibitions. Your adherence to prayer and fasting alone is not enough; there are other obligations such as the legitimate hijab and lowering the gaze. The door to repentance is open, and Allah rejoices at the repentance of His servant and replaces his bad deeds with good ones, so do not delay it.

It is also important to note: 1. Do not exaggerate your love for your suitor, because he is a human being and may make mistakes. 2. Your eagerness to mend your relationship with Allah must be greater than your eagerness for your relationship with people. 3. There are limits to the relationship between a suitor and his fiancée.
