Surah Al-Anfal Ayahs #47 Translated in English

[Remember, O Muḥammad], when Allāh showed them to you in your dream as few; and if He had shown them to you as many, you [believers] would have lost courage and would have disputed in the matter [of whether to fight], but Allāh saved [you from that]. Indeed, He is Knowing of that within the breasts.

And [remember] when He showed them to you, when you met, as few in your eyes, and He made you [appear] as few in their eyes so that Allāh might accomplish a matter already destined. And to Allāh are [all] matters returned.

O you who have believed, when you encounter a company [from the enemy forces], stand firm and remember Allāh much that you may be successful.

And obey Allāh and His Messenger, and do not dispute and [thus] lose courage and [then] your strength would depart; and be patient. Indeed, Allāh is with the patient.

And do not be like those who came forth from their homes insolently and to be seen by people and avert [them] from the way of Allāh. And Allāh is encompassing of what they do.
