How can one deal with the weakness of resistance in relationships with women, while maintaining the performance of religious duties and staying away from indecency?

The Prophet, peace and blessings be upon him, spoke truthfully when he said that the temptation of women is the most harmful temptation for men.

The questioner faces two matters: Sincere repentance for past negligence, and increasing acts of obedience and good deeds, for Allah Almighty said: "Indeed, good deeds do away with evil deeds."

As for the future, it is not permissible to go to places of corruption and intermingling, and one must avoid the causes and places of evil, adhere to righteous companionship, hasten to marry, commit to lowering the gaze, and ask Allah for protection from the temptation of women.
