Ahmed Raza Khan: Mohammed Aqib Qadri:
Till the time when they will see what they are promised -  so they will now come to know whose aide is weak, and who is lesser in number.

Yusuf Ali:
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.

Pickthal:
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.
