[Hence,] O you who have attained to faith, when you meet a host in battle, be firm, and remember God often; so that you might attain to a happy state! 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 Be not as those who went forth from their habitations swaggering boastfully to show off to men, and barring from God's way; and God encompasses the things they do. 47 And recall when Satan made their works seem fair to them and said: 'None shall overcome you today. and I am your supporter.' But when the two armies faced each other, he turned on his heels, and said: 'Surely I am quit of you for I behold that which you do not. Indeed I fear Allah, and Allah is stern in punishment.' 48
