Graves

9	84	وَلاَ تُصَلِّ عَلَى أَحَدٍ مِّنْهُم مَّاتَ أَبَدًا وَلاَ تَقُمْ عَلَىَ قَبْرِه إِنَّهُمْ كَفَرُواْ بِاللّهِ وَرَسُولِهِ وَمَاتُواْ وَهُمْ فَاسِقُونَ	And do not attend towards any of them when they have died, nor stand at their grave. They have rejected God and His messenger and died while they were wicked.
22	7	وَأَنَّ السَّاعَةَ آتِيَةٌ لَّا رَيْبَ فِيهَا وَأَنَّ اللَّهَ يَبْعَثُ مَن فِي الْقُبُورِ	And the Hour is coming, there is no doubt in it, and God will resurrect those who are in the graves.
35	22	وَمَا يَسْتَوِي الْأَحْيَاءُ وَلَا الْأَمْوَاتُ إِنَّ اللَّهَ يُسْمِعُ مَن يَشَاءُ وَمَا أَنتَ بِمُسْمِعٍ مَّن فِي الْقُبُورِ	Nor equal are the living and the dead; God causes whomever He wills to hear. And you cannot make those who are in the graves hear.
60	13	يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَوَلَّوْا قَوْمًا غَضِبَ اللَّهُ عَلَيْهِمْ قَدْ يَئِسُوا مِنَ الْآخِرَةِ كَمَا يَئِسَ الْكُفَّارُ مِنْ أَصْحَابِ الْقُبُورِ	O you who believe, do not ally a people with whom God is angry; for they have given-up regarding the Hereafter, just like the rejecters have given-up on the people who are already in the graves.
80	21	ثُمَّ أَمَاتَهُ فَأَقْبَرَهُ	Then He made him die and buried him.
82	4	وَإِذَا الْقُبُورُ بُعْثِرَتْ	And when the graves are laid open.
100	9	أَفَلَا يَعْلَمُ إِذَا بُعْثِرَ مَا فِي الْقُبُورِ	Does he not realise that when what is in the graves are scattered.
102	2	حَتَّى زُرْتُمُ الْمَقَابِرَ	Until you visit the graves.
