If you do not help him , yet God has helped him already , when the unbelievers drove him forth the second of two , when the two were in the Cave , when he said to his companion , ' Sorrow not ; surely God is with us . ' Then God sent down on him His Shechina , and confirmed him with legions you did not see ; and He made the word of the unbelievers the lowest ; and God 's word is the uppermost ; God is All-mighty , All-wise .
