Believers! When you encounter a party, remain firm and remember God much, so that you may succeed. 45 And pay heed unto God and His Apostle, and do not [allow yourselves to] be at variance with one another, lest you lose heart and your moral strength desert you. And be patient in adversity: for, verily, God is with those who are patient in adversity. 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 what time the Satan made their works fair-seeming unto them and said: there is none of mankind to overcome you today, and verily I am your neighbour. Then when the two parties faced each other, he turned on his heels, and said: verily I am quit of you, verily I behold that which ye behold not; verily I fear Allah: and Allah is severe in retribution. 48
