Ali 'Imran 3:126

Wama jaAAalahu Allahu illabushra lakum walitatma-inna quloobukum bihi wamaannasru illa min AAindi AllahialAAazeezi alhakeem

And Allāh made it not except as [a sign of] good tidings for you and to reassure your hearts thereby. And victory is not except from Allāh, the Exalted in Might, the Wise -

And Allah did this solely to make it a good news for you, and so that your hearts may be at rest with it. Otherwise, victory is from none but Allah, the All-Powerful, the All-Wise.
