those who deliberately commit major sins and neglect the pillar of Islam.
Prayer is the pillar of Islam. Consider what has been authentically established from the Prophet—may Allah bless him and grant him peace—through more than one route. When he was asked about someone for whom Hajj had become obligatory but who was unable to perform it, or who had vowed to fast or perform Hajj and then died—could it be performed on his behalf?—he replied:

The questioner said, “Yes.”
He said:
“Allah (1) has a greater right that what is owed to Him be discharged.” (2)
What he meant was that Allah has a greater right than human beings to accept fulfillment on behalf of someone with a valid excuse, for Allah is more merciful and more generous.

As for one who commits a major sin by deliberately allowing the prayer to lapse (5), he deserves neither alleviation nor mercy; but if he repents, then he has
