حَتَّىٰٓ إِذَا رَأَوْا۟ مَا يُوعَدُونَ فَسَيَعْلَمُونَ مَنْ أَضْعَفُ نَاصِرًۭا وَأَقَلُّ عَدَدًۭا
How to read it
Ḥattā 'idhā ra'aw' mā yūʻadūna fassayaʻ'lamūna man' 'aḍ'ʻafu nāṣiran wa'aqallu ʻadadan
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.
Translation: Abdullah Yusuf Ali
