Quran Al-Baqarah 2:104
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَقُولُواْ رَٰعِنَا وَقُولُواْ ٱنظُرۡنَا وَٱسۡمَعُواْۗ وَلِلۡكَٰفِرِينَ عَذَابٌ أَلِيمٞ
Translation
O you who have believed, say not [to Allāh's Messenger], "Rāʿinā" but say, "Unẓurnā" and listen. And for the disbelievers is a painful punishment.
