بَلِ السَّاعَةُ مَوْعِدُهُمْ وَالسَّاعَةُ أَدْهَى وَأَمَرُّ
[54:46]
Nay, the hour is their promised time, and the hour shall be most grievous and bitter.
Nay, the Hour (of Judgment) is the time promised them (for their full recompense): And that Hour will be most grievous and most bitter.
Nay, but the Hour (of doom) is their appointed tryst, and the Hour will be more wretched and more bitter (than their earthly failure).
