O believers, when you meet an army, stand firm, and think of God a great deal that you may be blessed with success. 45 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. 46 And be not like those who started from their homes insolently and to be seen of men, and to hinder (men) from the path of Allah: For Allah compasseth round about all that they do. 47 And when the Shaitan made their works fair seeming to them, and said: No one can overcome you this day, and surely I am your protector: but when the two parties came in sight of each other he turned upon his heels, and said: Surely I am clear of you, surely I see what you do not see, surely I fear Allah; and Allah is severe in requiting (evil). 48
