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 And be not like those [unbelievers] who went forth from their homelands full of self-conceit and a desire to be seen and praised by men for they were trying to turn others away from the path of God - the while God encompassed all their doings [with His might]. 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
