O you who have believed, fear Allah as He should be feared and do not die except as Muslims [in submission to Him].

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ ٱللَّهَ حَقَّ تُقَاتِهِۦ وَلَا تَمُوتُنَّ إِلَّا وَأَنتُم مُّسْلِمُونَO you who have believed, fear Allah as He should be feared and do not die except as Muslims [in submission to Him].
