30وَلَو نَشاءُ لَأَرَيناكَهُم فَلَعَرَفتَهُم بِسيماهُم ۚ وَلَتَعرِفَنَّهُم في لَحنِ القَولِ ۚ وَاللَّهُ يَعلَمُ أَعمالَكُم(Irfan-ul-Quran)And if We will We can surely show these (hypocrites) to you (in such a manner) that you may recognize them by their facial expressions and (likewise) you may recognize them by their conversation style and Allah knows (best) all your actions.
