Is one absolved of responsibility by adopting the opinion that missed prayers do not need to be made up? And does the hadith, "Look and see if My servant has any supererogatory deeds," apply to one who has not repented? And do supererogatory prayers compensate for abandoned prayers?

The summary of the fatwa is that the Muslim who intentionally abandons prayer is not required to make it up according to the majority of scholars. The preponderant opinion is that whoever abandons prayer until its time expires without a valid excuse is not obligated to make it up. Their repentance lies in regretting it, resolving to observe it consistently, and performing many supererogatory prayers, because Allah Almighty will compensate for deficiencies in obligatory prayers with supererogatory ones on the Day of Judgment.
