When they come to you, they say, “We believe,” even though they were full of disbelief when they entered, and they are full of disbelief when they leave. God is fully aware of everything they conceal.
وَإِذا جاءوكُم قالوا ءامَنّا وَقَد دَخَلوا بِالكُفرِ وَهُم قَد خَرَجوا بِهِ وَاللَّهُ أَعلَمُ بِما كانوا يَكتُمونَ
wa izaa jaaa’ookum qaalooo aamannaa wa qad dakhaloo bilkufri wa hum qad kharajoo bih; wallaahu a’lamu bimaa kaanoo yaktumoon
