وَلَا تُصَلِّ عَلَىٰٓ أَحَدٍ مِّنْهُم مَّاتَ أَبَدًا وَلَا تَقُمْ عَلَىٰ قَبْرِهِۦٓ ۖ إِنَّهُمْ كَفَرُوا۟ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُوا۟ وَهُمْ فَـٰسِقُونَ٨٤
And do not pray [the funeral prayer, O Muḥammad], over any of them who has died - ever - or stand at his grave. Indeed, they disbelieved in Allāh and His Messenger and died while they were defiantly disobedient.
