Surah Muhammad, Verse 30

وَلَوۡ نَشَآءُ لَأَرَيۡنَٰكَهُمۡ فَلَعَرَفۡتَهُم بِسِيمَٰهُمۡۚ وَلَتَعۡرِفَنَّهُمۡ فِي لَحۡنِ ٱلۡقَوۡلِۚ وَٱللَّهُ يَعۡلَمُ أَعۡمَٰلَكُمۡ٣٠

walaw nashāu la-araynākahum falaʿaraftahum bisīmāhum walataʿrifannahum fī laḥni l-qawli wal-lahu yaʿlamu aʿmālakum

And if We willed, We could show them to you, and you would know them by their mark; but you will surely know them by the tone of [their] speech. And Allāh knows your deeds.
