Al-Qamar 54:46
بَلِ ٱلسَّاعَةُ مَوْعِدُهُمْ وَٱلسَّاعَةُ أَدْهَىٰ وَأَمَرُّ
Bali assaAAatu mawAAiduhum wassaAAatuadha waamar
But the Hour is their appointment [for due punishment], and the Hour is more disastrous and more bitter.
Rather the Hour (of judgment) is their appointed time (for their full recompense), and the Hour is more calamitous and much more bitter.
