وَلَوْ نَشَاءُ لَأَرَيْنَاكَهُمْ فَلَعَرَفْتَهُمْ بِسِيمَاهُمْ ۚ وَلَتَعْرِفَنَّهُمْ فِي لَحْنِ الْقَوْلِ ۚ وَاللَّهُ يَعْلَمُ أَعْمَالَكُمْ

Surah Muhammad : 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.
