Surah Hud — Ayah 21 (11:21)
أُوْلَٰٓئِكَ ٱلَّذِينَ خَسِرُوٓاْ أَنفُسَهُمۡ وَضَلَّ عَنۡهُم مَّا كَانُواْ يَفۡتَرُونَ ٢١
English translation (Saheeh International)
Those are the ones who will have lost themselves, and lost from them is what they used to invent.
Brief commentary
These are people who have lost themselves, heading towards their own ruin through associating partners with Allah; and the partners and intercessors they have invented will abandon them.
