At Tawbah, 84 Ayah
9:84
وَلَا تُصَلِّ عَلَىٰٓ أَحَدٖ مِّنۡهُم مَّاتَ أَبَدٗا وَلَا تَقُمۡ عَلَىٰ قَبۡرِهِۦٓۖ إِنَّهُمۡ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦ وَمَاتُواْ وَهُمۡ فَٰسِقُونَ ٨٤
Wa Lā Tuşalli `Alá 'Aĥadin Minhum Māta 'Abadāan Wa Lā Taqum `Alá Qabrihi ۖ 'Innahum Kafarū Bil-Lahi Wa Rasūlihi Wa Mātū Wa Hum Fāsiqūna
And do not pray [the funeral prayer, O Muhammad], over any of them who has died - ever - or stand at his grave. Indeed, they disbelieved in Allah and His Messenger and died while they were defiantly disobedient.
