Is the worship and prayer of a committed person accepted if they commit sins such as kissing and embracing someone of the opposite sex under the pretext of affection and intention of marriage?

Those whom Allah has favored with guidance are the foremost among people to adhere to Allah's commands, and it is not befitting for them to follow the footsteps of Satan. Knowing what is forbidden does not prevent one from falling into it, and the responsibility of one who knows is greater. It is obligatory to remind friends of the ugliness of what they are doing, especially if they outwardly appear to be committed. Excusing oneself with affection towards friends is following whims, and Islamic law forbids taking close companions (أخدان) for both men and women.
