Al-Baqarah - 2:9

يُخَادِعُونَ اللّهَ وَالَّذِينَ آمَنُوا وَمَا يَخْدَعُونَ إِلاَّ أَنفُسَهُم وَمَا يَشْعُرُونَ
[2:9]
They desire to deceive Allah and those who believe, and they deceive only themselves and they do not perceive.
Fain would they deceive Allah and those who believe, but they only deceive themselves, and realise (it) not!
They think to beguile Allah and those who believe, and they beguile none save themselves; but they perceive not.
