Surah Al-Anfal Ayahs #49 Translated in English

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.

And [remember] when Satan made their deeds pleasing to them and said, "No one can overcome you today from among the people, and indeed, I am your protector." But when the two armies sighted each other, he turned on his heels and said, "Indeed, I am disassociated from you. Indeed, I see what you do not see; indeed, I fear Allāh. And Allāh is severe in penalty."

[Remember] when the hypocrites and those in whose hearts was disease [i.e., arrogance and disbelief] said, "Their religion has deluded those [Muslims]." But whoever relies upon Allāh - then indeed, Allāh is Exalted in Might and Wise.
