وَإِذَا جَاءُوكُمْ قَالُوا آمَنَّا وَقَدْ دَخَلُوا بِالْكُفْرِ وَهُمْ قَدْ خَرَجُوا بِهِ ۚ وَاللَّهُ أَعْلَمُ بِمَا كَانُوا يَكْتُمُونَ 61
When they come to thee, they say: "We believe": but in fact they enter with a mind against Faith, and they go out with the same but Allah knoweth fully all that they hide.
