وَلَوْ نَشَاءُ لَأَرَيْنَاكَهُمْ فَلَعَرَفْتَهُمْ بِسِيمَاهُمْ ۚ وَلَتَعْرِفَنَّهُمْ فِي لَحْنِ الْقَوْلِ ۚ وَاللَّهُ يَعْلَمُ أَعْمَالَكُمْ 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 Allah knows your deeds.
