The unseen assistance of Allah ﷻ (exalted is His majesty) (Khandaq), added by this site

Allah ﷻ (exalted is His majesty) assisted the Muslim army in this trying moment and sent a strong wind that uprooted the tents of the disbelievers from the ground and overturned their pots that were over blazing fires. This left the disbelievers devastated and without any provisions. Furthermore, Nu’aim bin Mas’ood رضي الله عنه (may Allah be pleased with him) had carried out a strategic plan that caused confusion and disunity amongst the ranks of the kuffar army. Thus, the kuffar were totally uprooted and fled the battlefield.
