Al-Maaida 5:61

وَإِذَا جَآءُوكُمْ قَالُوٓا۟ ءَامَنَّا وَقَد دَّخَلُوا۟ بِٱلْكُفْرِ وَهُمْ قَدْ خَرَجُوا۟ بِهِۦ ۚ وَٱللَّهُ أَعْلَمُ بِمَا كَانُوا۟ يَكْتُمُونَ

Wa izaa jaaa'ookum qaalooo aamannaa wa qad dakhaloo bilkufri wa hum qad kharajoo bih; wallaahu a'lamu bimaa kaanoo yaktumoon

Whenever they come to you they say: 'We believe,' whereas, in fact, they come disbelieving, and go away disbelieving, and Allah knows all that they hide.
