YUSUFALI: Remember thy Lord inspired the angels (with the message): I am with you: give firmness to the Believers: I will instil terror into the hearts of the Unbelievers: smite ye above their necks and smite all their finger-tips off them.
Then the Jihad Hadiths
Allahs Apostle said, I have been sent with the shortest expressions bearing the widest meanings, and I have been made victorious with terror (cast in the hearts of the enemy), and while I was sleeping, the keys of the treasures of the world were brought to me and put in my hand. Abu Huraira added: Allahs Apostle has left the world and now you, people, are bringing out those treasures (i.e. the Prophet did not benefit by them).
