3:102
يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ ٱتَّقُوا۟ ٱللَّهَ حَقَّ تُقَاتِهِۦ وَلَا تَمُوتُنَّ إِلَّا وَأَنتُم مُّسْلِمُونَ
yāayyuhā alladhīna āmanū ittaqū l-laha ḥaqqa tuqātihi walā tamūtunna illā wa-antum mus'limūna
You who believe, be mindful of God, as is His due, and make sure you devote yourselves to Him, to your dying moment.
O you who believe! Fear Allâh (by doing all that He has ordered and by abstaining from all that He has forbidden) as He should be feared. [Obey Him, be thankful to Him, and remember Him always], and die not except in a state of Islâm [as Muslims (with complete submission to Allâh)].
