[The disbelievers continue] until, when they see that which they are promised, then they will know who is weaker in helpers and less in number.
The Saheeh International Quran Translation
حَتَّىٰٓ إِذَا رَأَوْا۟ مَا يُوعَدُونَ فَسَيَعْلَمُونَ مَنْ أَضْعَفُ نَاصِرًا وَأَقَلُّ عَدَدًا[The disbelievers continue] until, when they see that which they are promised, then they will know who is weaker in helpers and less in number.
