Surah Al-Baqarah, Verse 104

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَقُولُواْ رَٰعِنَا وَقُولُواْ ٱنظُرۡنَا وَٱسۡمَعُواْۗ وَلِلۡكَٰفِرِينَ عَذَابٌ أَلِيمٞ١٠٤

yāayyuhā alladhīna āmanū lā taqūlū rāʿinā waqūlū unẓur'nā wa-is'maʿū walil'kāfirīna ʿadhābun alīmun

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.
