30وَلَو نَشاءُ لَأَرَيناكَهُم فَلَعَرَفتَهُم بِسيماهُم ۚ وَلَتَعرِفَنَّهُم في لَحنِ القَولِ ۚ وَاللَّهُ يَعلَمُ أَعمالَكُم(Saheeh International)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.
