Quran 33:19 — The Parties (Al-Ahzab)

Also, they are too stingy when dealing with you. If anything threatens the community, you see their eyes rolling with fear, as if death had already come to them. Once the crisis is over, they whip you with sharp tongues. They are too stingy with their wealth. These are not believers, and, consequently, GOD has nullified their works. This is easy for GOD to do.

[33:18] GOD is fully aware of the hinderers among you, and those who say to their comrades, "Let us all stay behind." Rarely do they mobilize for defense.

[33:20] They thought that the parties might come back. In that case, they would wish that they were lost in the desert, asking about your news from afar. Had the parties attacked you while they were with you, they would rarely support you.
