Qur'an 47:30 · Muhammad

وَلَوْ نَشَآءُ لَأَرَيْنَٰكَهُمْ فَلَعَرَفْتَهُم بِسِيمَٰهُمْ ۚ وَلَتَعْرِفَنَّهُمْ فِى لَحْنِ ٱلْقَوْلِ ۚ وَٱللَّهُ يَعْلَمُ أَعْمَٰلَكُمْ

(30) 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.
