Surah 84. The Sundering, Splitting Open
21. And when the Qur'an is read to them, they fall not prostrate,
22. But on the contrary the Unbelievers reject (it).
23. But Allah has full knowledge of what they secrete (in their breasts)
24. So announce to them a Penalty Grievous,
25. Except to those who believe and work righteous deeds: For them is a Reward that will never fail.
