الماۤئدة — Al-Ma'idah Ayat 61
وَاِذَا جَاۤءُوْكُمْ قَالُوْٓا اٰمَنَّا وَقَدْ دَّخَلُوْا بِالْكُفْرِ وَهُمْ قَدْ خَرَجُوْا بِهٖ ۗوَاللّٰهُ اَعْلَمُ بِمَا كَانُوْا يَكْتُمُوْنَ
Wa iżā jā'ūkum qālū āmannā wa qad dakhalū bil-kufri wa hum qad kharajū bih(ī), wallāhu a‘lamu bimā kānū yaktumūn(a).
"And when they come to you, they say, "We believe." But they have entered with disbelief [in their hearts], and they have certainly left with it. And Allah is most knowing of what they were concealing."
