وَلَوْ نَشَآءُ لَأَرَيْنَٰكَهُمْ فَلَعَرَفْتَهُم بِسِيمَٰهُمْ ۚ وَلَتَعْرِفَنَّهُمْ فِى لَحْنِ ٱلْقَوْلِ ۚ وَٱللَّهُ يَعْلَمُ أَعْمَٰلَكُمْ
Had We so wiled, We could have shown them up to thee, and thou shouldst have known them by their marks: but surely thou wilt know them by the tone of their speech! And Allah knows all that ye do.
