39:41
إِنَّآ أَنزَلْنَا عَلَيْكَ ٱلْكِتَـٰبَ لِلنَّاسِ بِٱلْحَقِّ ۖ فَمَنِ ٱهْتَدَىٰ فَلِنَفْسِهِۦ ۖ وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا ۖ وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ
Indeed, We sent down to you the Book for the people in truth. So whoever is guided - it is for [the benefit of] his soul; and whoever goes astray only goes astray to its detriment. And you are not a manager over them.

قُلْ يَـٰقَوْمِ ٱعْمَلُوا۟ عَلَىٰ مَكَانَتِكُمْ إِنِّى عَـٰمِلٌ ۖ فَسَوْفَ تَعْلَمُونَ
Say, "O my people, work according to your position, [for] indeed, I am working; and you are going to know
مَن يَأْتِيهِ عَذَابٌ يُخْزِيهِ وَيَحِلُّ عَلَيْهِ عَذَابٌ مُّقِيمٌ
To whom will come a torment disgracing him and on whom will descend an enduring punishment."
ٱللَّهُ يَتَوَفَّى ٱلْأَنفُسَ حِينَ مَوْتِهَا وَٱلَّتِى لَمْ تَمُتْ فِى مَنَامِهَا ۖ فَيُمْسِكُ ٱلَّتِى قَضَىٰ عَلَيْهَا ٱلْمَوْتَ وَيُرْسِلُ ٱلْأُخْرَىٰٓ إِلَىٰٓ أَجَلٍ مُّسَمًّى ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّقَوْمٍ يَتَفَكَّرُونَ
Allah takes the souls at the time of their death, and those that do not die [He takes] during their sleep. Then He keeps those for which He has decreed death and releases the others for a specified term. Indeed in that are signs for a people who give thought.
أَمِ ٱتَّخَذُوا۟ مِن دُونِ ٱللَّهِ شُفَعَآءَ ۚ قُلْ أَوَلَوْ كَانُوا۟ لَا يَمْلِكُونَ شَيْـًٔا وَلَا يَعْقِلُونَ
Or have they taken other than Allah as intercessors? Say, "Even though they do not possess [power over] anything, nor do they reason?"
