Quran 18:15. WORSHIP requires AUTHORITY from Allah, Al-Ilaha.

هَٰؤُلَاءِ قَوْمُنَا اتَّخَذُوا مِن دُونِهِ آلِهَةً ۖ لَّوْلَا يَأْتُونَ عَلَيْهِم بِسُلْطَانٍ بَيِّنٍ ۖ فَمَنْ أَظْلَمُ مِمَّنِ افْتَرَىٰ عَلَى اللَّهِ كَذِبًا These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah a lie?” Bangla এরা […]

53:23 THOUGHTS and IDEAS about Allah which HE did not AUTHORISE (approve) is from men’s own DESIRE.

They are not but [mere] names you have named them – you and your forefathers – for which Allah has sent down no authority. They follow not except assumption and what [their] souls desire, and there has already come to them from their Lord guidance.

Quran 31:21. FOLLOW only what Allah has sent, NOT your Forefather’s ways.

“Follow what Allah has revealed,” they say, “Rather, we will follow that upon which we found our fathers.” Even if Satan was inviting them to the punishment of the Blaze?
