Quran 9:84 At-Tawbah, ayah 84 of 129

وَلَا تُصَلِّ عَلَىٰٓ أَحَدٍ مِّنْهُم مَّاتَ أَبَدًا وَلَا تَقُمْ عَلَىٰ قَبْرِهِۦٓ ۖ إِنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُوا۟ وَهُمْ فَـٰسِقُونَ ۝٨٤

9:84 And never (O Muhammad) pray for one of them who dieth, nor stand by his grave. Lo! they disbelieved in Allah and His messenger, and they died while they were evil-doers.
