(Al-Muaminoon) 23 : 117
وَمَنْ يَدْعُ مَعَ اللَّهِ إِلَٰهًا آخَرَ لَا بُرْهَانَ لَهُ بِهِ فَإِنَّمَا حِسَابُهُ عِنْدَ رَبِّهِ ۚ إِنَّهُ لَا يُفْلِحُ الْكَافِرُونَ
And whoever invokes deities along with Lord Allah for which he has no Proof, then indeed his account is with his Lord; indeed, He will not make prosper the disbelievers.
The Proof is one among the 40 names of Adhikr. The Arabic Quran reading Fujjar who invoke others along with Lord are the disbelievers, wrongdoers, and transgressors. They are earning Hell as a fine for their aimless and heedless life in this world as explained in verses 9: 67-68 and 25: 65-66. Verse 6: 21 ends as: “He will not make prosper the wrongdoers”; and verse 10: 17 ends as: “He will not make prosper the Mujirims”. See explanation 4: 174-175; 21: 24; 22: 62 and 25: 68-70.
