Quran 33:14 — The Parties (Al-Ahzab)

Had the enemy invaded and asked them to join, they would have joined the enemy without hesitation.

[33:13] A group of them said, "O people of Yathrib, you cannot attain victory; go back." Others made up excuses to the prophet: "Our homes are vulnerable," when they were not vulnerable. They just wanted to flee.

[33:15] They had pledged to GOD in the past that they would not turn around and flee; making a pledge with GOD involves a great responsibility.
