Az-Zumar 39:42

إِنَّآ أَنزَلْنَا عَلَيْكَ الْكِتَبَ

(Verily, We have sent down to you the Book) meaning, the Qur'an.

لِلنَّاسِ بِالْحَق

(for mankind in truth.) means, for all of creation, mankind and Jinn, so that he may warn them therewith.

فَمَنِ اهْتَدَى فَلِنَفْسِهِ

(So, whosoever accepts the guidance, it is only for himself;) means, the benefit of that will return to him.

وَمَن ضَلَّ فَإِنَّمَا يَضِلُّ عَلَيْهَا

(and whosoever goes astray, he goes astray only for his (own) loss.) means, the consequences of that will return to him.

وَمَآ أَنتَ عَلَيْهِم بِوَكِيلٍ

(And you are not a trustee over them. ) means, `you are not responsible for guiding them.'

إِنَّمَآ أَنتَ نَذِيرٌ وَاللَّهُ عَلَى كُلِّ شَىْءٍ وَكِيلٌ

(But you are only a warner. And Allah is a Trustee over all things) (11:12).

فَإِنَّمَا عَلَيْكَ الْبَلَغُ وَعَلَيْنَا الْحِسَابُ

(your duty is only to convey and on Us is the reckoning) (13:40).

Allah is the One Who causes Death and gives Life

Then Allah tells us that He is in control of all things and does as He wills. He causes men to die (the "greater death") when He sends the angels to take men's souls from their bodies, and He causes them to "die a lesser death" when they sleep. Allah says:

وَهُوَ الَّذِى يَتَوَفَّكُم بِالَّيْلِ وَيَعْلَمُ مَا جَرَحْتُم بِالنَّهَارِ ثُمَّ يَبْعَثُكُمْ فِيهِ لِيُقْضَى أَجَلٌ مّسَمًّى ثُمَّ إِلَيْهِ مَرْجِعُكُمْ ثُمَّ يُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ - وَهُوَ الْقَاهِرُ فَوْقَ عِبَادِهِ وَيُرْسِلُ عَلَيْكُم حَفَظَةً حَتَّى إِذَا جَآءَ أَحَدَكُمُ الْمَوْتُ تَوَفَّتْهُ رُسُلُنَا وَهُمْ لاَ يُفَرِّطُونَ

(It is He, Who takes your souls by night (when you are asleep), and has knowledge of all that you have done by day, then He raises (wakes) you up again that a term appointed be fulfilled, then (in the end) unto Him will be your return. Then He will inform you of that which you used to do. He is the Irresistible, over His servants, and He sends guardians (angels guarding and writing all of one's good and bad deeds) over you, until when death approaches one of you, Our messengers (angels) take his soul, and they never neglect their duty.)(6:60-61). Here Allah mentions the two deaths, the lesser death then the greater death after it; in the Ayah above (39: 42), He mentions the greater then the lesser. Allah says:

اللَّهُ يَتَوَفَّى الاٌّنفُسَ حِينَ مِوْتِهَا وَالَّتِى لَمْ تَمُتْ فِى مَنَامِهَا فَيُمْسِكُ الَّتِى قَضَى عَلَيْهَا الْمَوْتَ وَيُرْسِلُ الاٍّخْرَى إِلَى أَجَلٍ مُّسَمًّى

(It is Allah Who takes away the souls at the time of their death, and those that die not during their sleep. He keeps those (souls) for which He has ordained death and sends the rest for a term appointed.) This indicates that they the souls meet in the higher realm, as was stated in the Hadith attributed to the Prophet which was narrated by Ibn Mandah and others. In the Two Sahihs of Al-Bukhari and Muslim, it is reported that Abu Hurayrah, may Allah be pleased with him, said that the Messenger of Allah ﷺ said:

«إِذَا أَوَى أَحَدُكُمْ إِلى فِرَاشِهِ فَلْيَنْفُضْهُ بِدَاخِلَةِ إِزَارِهِ، فَإِنَّهُ لَا يَدْرِي مَا خَلَفَهُ عَلَيْهِ، ثُمَّ لِيَقُلْ: بِاسْمِكَ رَبِّي وَضَعْتُ جَنْبِي، وَبِكَ أَرْفَعُهُ، إِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا، وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِين»

(When anyone of you goes to bed, let him brush down the bed with his garment, for he does not know what has come on his bed since he left it. Then let him say, "In Your Name, O Lord, I lay down my side and in Your Name I raise it up; if You take my soul, have mercy on it, and if You send it back, protect it with that which You protect Your righteous servants.")

فَيُمْسِكُ الَّتِى قَضَى عَلَيْهَا الْمَوْتَ

(He keeps those (souls) for which He has ordained death) means, those which have died, and He returns the others back for an appointed term. As-Suddi said, "For the rest of their lives." Ibn `Abbas, may Allah be pleased with him, said, "He keeps the souls of the dead and sends back the souls of the living, and He does not make any mistakes.

إِنَّ فِى ذلِكَ لآيَتٍ لِّقَوْمٍ يَتَفَكَّرُونَ

(Verily, in this are signs for a people who think deeply.)
