Allah made this ruling easy for them and abrogated this Ayah with another Ayah,

اﻻن خفف الله عنكم وعلم أن فيكم ضعفا

Now Allah has lightened your (task), for He knows that there is weakness in you... Thereafter, if Muslims were half as many as their enemy, they were not allowed to run away from them. If the Muslims were fewer than that, they were not obligated to fight the disbelievers and thus allowed to avoid hostilities.''

وإن يكن منكم ألف يغلبوا ألفين بٳذن الله

and if there are a thousand of you, they shall overcome two thousand by the leave of Allah.

والله مع الصابرين

And Allah is with the patient
