Surah At-Taubah (The Repentance), Verse 84

وَلَا تُصَلِّ عَلٰۤی اَحَدٍ مِّنْهُمْ مَّاتَ اَبَدًا وَّلَا تَقُمْ عَلٰی قَبْرِهٖ اِنَّهُمْ كَفَرُوْا بِاللّٰهِ وَرَسُوْلِهٖ وَمَاتُوْا وَهُمْ فٰسِقُوْنَ ۟

Wa laa tusalli 'alaaa ahadim minhum maata abadanw wa laa taqum 'alaa qabriheee innahum kafaroo billaahi wa Rasoolihee wa maatoo wa hum faasiqoon

“Nor do thou ever pray for any of them that dies, nor stand at his grave; for they rejected Allah and His Messenger, and died in a state of perverse rebellion.”
