Al-Anfaal — Ruku 6

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

And obey Allah and His Messenger, and do not dispute and [thus] lose courage and [then] your strength would depart; and be patient. Indeed, Allah 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 Allah. And Allah 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 Allah. And Allah is severe in penalty."
