(Al-Ma’aarij) 70 : 1
بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ سَأَلَ سَائِلٌ بِعَذَابٍ وَاقِعٍ
A questioner asks you about the punishment bound to happen.
Those who have no confirmed belief about the happening of what is told in Adhikr which is the Confirming Truth are asking about the punishment that is going to affect them. Since the believers have understood from this world itself from Adhikr-the Three Time Knowledge about everything that will happen in the Hereafter, they are having confirmed belief about the Hereafter as explained in verses 2: 2-5. See explanation 42: 18; and 52: 7.
