Believers, when you meet an army stand firm and remember Allah abundantly, in order that you are prosperous. 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 Do not be like those who went out of their homes full of their own importance, ostentatiously, trying to hinder others from the way of God. But God encompasses all 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
