Nobel Quran - English Translation
149. O ye who believe ! if you obey those who have disbelieved, they will cause you to turn back on your heels, and you will become the losers.
150. Nay, ALLAH is your Protector, and HE is the Best of helpers.
151. And WE shall cast terror into the hearts of those who disbelieved because they associate partners with ALLAH, for which HE has sent down no authority. Their abode is the Fire; and evil is the habitation of the wrongdoers.
152. And ALLAH had surely made good to you HIS promise when you were slaying and destroying them by HIS leave, until, when your courage failed you and you disputed among yourselves concerning the order and you disobeyed, after HE had shown you that which you love, HE withdrew HIS help. Among you were those who desired the present world, and among you were those who desired the Hereafter. Then HE turned you away from them, that HE might try you - and HE has surely pardoned you, and ALLAH is Gracious to the believers -
153. When you were running away and looked not back at anyone while the Messenger was calling you, in your rear, then HE gave you one sorrow after another sorrow, that you might not grieve for what escaped you nor for what befell you. And ALLAH is quite Aware of what you do.
