Al-Jinn - 72:24

حَتَّى إِذَا رَأَوْا مَا يُوعَدُونَ فَسَيَعْلَمُونَ مَنْ أَضْعَفُ نَاصِرًا وَأَقَلُّ عَدَدًا
[72:24]
Until when they see what they are threatened with, then shall they know who is weaker in helpers and fewer in number.
At length, when they see (with their own eyes) that which they are promised,- then will they know who it is that is weakest in (his) helper and least important in point of numbers.
Till (the day) when they shall behold that which they are promised (they may doubt); but then they will know (for certain) who is weaker in allies and less in multitude.
