Tafsir of Muhammad 47:7

{If you aid} the religion of {Allah} and His Messenger, {He will aid you} against your enemy, grant you victory, {and plant your feet firmly} on the battlefields or upon the path of Islam.

{And those who disbelieve, for them is destruction, and He has led their deeds astray. That is because they disliked what Allah has revealed, so He rendered their deeds worthless.}
