Quran 33:13 — The Parties (Al-Ahzab)

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.

[33:12] The hypocrites and those with doubts in their hearts said, "What GOD and His messenger promised us was no more than an illusion!"

[33:14] Had the enemy invaded and asked them to join, they would have joined the enemy without hesitation.
