If you do not help him , Allah will help him as He helped him when he was driven out with one other ( Abu Bakr ) by the unbelievers . When the two were in the cave , he said to his companion : ' Do not sorrow , Allah is with us ' Then Allah caused His tranquility ( shechina ) to descend upon him and supported him with legions ( of angels ) you did not see , and He made the word of the unbelievers the lowest , and the Word of Allah is the highest .
