Qur'an 3:145

وَمَا كَانَ لِنَفْسٍ أَن تَمُوتَ إِلَّا بِإِذْنِ ٱللَّهِ كِتَـٰبًا مُّؤَجَّلًا ۗ وَمَن يُرِدْ ثَوَابَ ٱلدُّنْيَا نُؤْتِهِۦ مِنْهَا وَمَن يُرِدْ ثَوَابَ ٱلْـَٔاخِرَةِ نُؤْتِهِۦ مِنْهَا ۚ وَسَنَجْزِى ٱلشَّـٰكِرِينَ

No soul can ever die except by Allah's leave and at a term appointed. Whoso desireth the reward of the world, We bestow on him thereof; and whoso desireth the reward of the Hereafter, We bestow on him thereof. We shall reward the thankful.
