Denying Resurrection after Death, is Strange
Allah says to His Messenger Muhammad ﷺ .
وَإِن تَعْجَبْ
(And if you wonder.) at the rejection of the polytheists who deny Resurrection, even though they witness Allah's signs and evidences that He made in His creation which testify that He is able to do everything. Yet, they admit that Allah originated the creation of all things and brought them into existence after they were nothing. However, they deny Allah's claim that He will resurrect the world anew, even though they admit to what is more amazing than what they deny and reject. Therefore, it is amazing that they said,
أَءِذَا كُنَّا تُرَابًا أَءِنَّا لَفِى خَلْقٍ جَدِيدٍ
(When we are dust, shall we indeed then be (raised) in a new creation) It is an obvious fact to every sane and knowledgeable person that creating the heavens and earth is a greater feat than creating men, and that He Who has originated creation is more able to resurrect it anew,
أَوَلَمْ يَرَوْاْ أَنَّ اللَّهَ الَّذِى خَلَقَ السَّمَـوَتِ وَالاٌّرْضِ وَلَمْ يَعْىَ بِخَلْقِهِنَّ بِقَادِرٍ عَلَى أَن يُحْىِ الْمَوْتَى بَلَى إِنَّهُ عَلَى كُلِّ شَىْءٍ قَدِيرٌ
(Do they not see that Allah, Who created the heavens and the earth, and was not wearied by their creation, is able to give life to the dead Yes, He surely is able to do all things)46:33 Allah described those who deny Resurrection,
أُوْلَـئِكَ الَّذِينَ كَفَرُواْ بِرَبِّهِمْ وَأُوْلَئِكَ الاٌّغْلَـلُ فِى أَعْنَـقِهِمْ
(They are those who disbelieved in their Lord! They are those who will have iron chains linking their hands to their necks. ) They will be dragged in the Fire by these chains,
وَأُوْلـئِكَ أَصْحَـبُ النَّارِ هُمْ فِيهَا خَـلِدُونَ
(They will be dwellers of the Fire to abide therein forever.), for they will remain in Hell forever and will never escape it or be removed from it.
وَيَسْتَعْجِلُونَكَ بِالسَّيِّئَةِ قَبْلَ الْحَسَنَةِ وَقَدْ خَلَتْ مِن قَبْلِهِمُ الْمَثُلَـتُ وَإِنَّ رَبَّكَ لَذُو مَغْفِرَةٍ لِّلنَّاسِ عَلَى ظُلْمِهِمْ وَإِنَّ رَبَّكَ لَشَدِيدُ الْعِقَابِ
