Surat Al-Ahzaab (The Clans) - الأحزاب

وَإِذْ يَقُولُ ٱلْمُنَٰفِقُونَ وَٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ مَّا وَعَدَنَا ٱللَّهُ وَرَسُولُهُۥٓ إِلَّا غُرُورًا ﴿١٢﴾

And when the hypocrites and those in whose hearts was a disease began to say: Allah and His Apostle did not promise us (victory) but only to deceive.
