Quran 33:10 — The Parties (Al-Ahzab)

إِذ جاءوكُم مِن فَوقِكُم وَمِن أَسفَلَ مِنكُم وَإِذ زاغَتِ الأَبصٰرُ وَبَلَغَتِ القُلوبُ الحَناجِرَ وَتَظُنّونَ بِاللَّهِ الظُّنونا۠

When they came from above you, and from beneath you, your eyes were terrified, your hearts ran out of patience, and you harbored unbefitting thoughts about GOD.

[33:9] O you who believe, remember GOD's blessing upon you; when soldiers attacked you, we sent upon them violent wind and invisible soldiers. GOD is Seer of everything you do.

[33:11] That is when the believers were truly tested; they were severely shaken up.
