سُورَةُ المَائـِدَةِ
Surah Al-Maaida·5:61
وَإِذَا جَاءُوكُمْ قَالُوا آمَنَّا وَقَدْ دَخَلُوا بِالْكُفْرِ وَهُمْ قَدْ خَرَجُوا بِهِ ۚ وَاللَّهُ أَعْلَمُ بِمَا كَانُوا يَكْتُمُونَ٦١
For, when they come unto you, they say, "We do believe": whereas, in fact, they come with the resolve to deny the truth, and depart in the same state. But God is fully aware of all that they would conceal.
