Muhammad Ayah 30

وَلَوْ نَشَآءُ لَأَرَيْنَـٰكَهُمْ فَلَعَرَفْتَهُم بِسِيمَـٰهُمْ‌ۚ وَلَتَعْرِفَنَّهُمْ فِى لَحْنِ ٱلْقَوْلِ‌ۚ وَٱللَّهُ يَعْلَمُ أَعْمَـٰلَكُمْ ٣٠ Had We willed, We could have truly shown them to you ?O Prophet?, and you would have certainly recognized them by their appearance. But you will surely recognize them by their tone of speech. And Allah ?fully? knows your doings ?O people?.
