At Tawbah Ayah 84

وَلَا تُصَلِّ عَلَىٰٓ أَحَدٍ مِّنْهُم مَّاتَ أَبَدًا وَلَا تَقُمْ عَلَىٰ قَبْرِهِۦٓ‌ۖ إِنَّهُمْ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُواْ وَهُمْ فَـٰسِقُونَ ٨٤ And do not ever offer ?funeral? prayers for any of their dead, nor stand by their grave ?at burial?, for they have lost faith in Allah and His Messenger and died rebellious.
