Quran 23:109 — The Believers (Al-Mu'minun)

إِنَّهُ كانَ فَريقٌ مِن عِبادى يَقولونَ رَبَّنا ءامَنّا فَاغفِر لَنا وَارحَمنا وَأَنتَ خَيرُ الرّٰحِمينَ

"A group of My servants used to say, 'Our Lord, we have believed, so forgive us and shower us with mercy. Of all the merciful ones, You are the Most Merciful.'

[23:108] He will say, "Abide therein, humiliated, and do not speak to Me.

[23:110] "But you mocked and ridiculed them, to the extent that you forgot Me. You used to laugh at them.
