Ali 'Imran · 3:122

122. Remember, O Prophet, what happened to two groups of the believers from Banī Salamah and Banī Ḥārithah, when they became weak and almost withdrew when the hypocrites drew back; but Allah aided them, making them firm in fighting, and turning them away from what they had been on the edge of doing. So, let those who have faith look to Allah alone for support, no matter what may happen to them.
