(Thwaha) 20 : 90
وَلَقَدْ قَالَ لَهُمْ هَارُونُ مِنْ قَبْلُ يَا قَوْمِ إِنَّمَا فُتِنْتُمْ بِهِ ۖ وَإِنَّ رَبَّكُمُ الرَّحْمَٰنُ فَاتَّبِعُونِي وَأَطِيعُوا أَمْرِي
And Haroon had already told them before: "Oh my people! You are only being tested by it, and indeed your Lord is the Impartial, so you follow me and you obey my commands".
Impartial Lord doesn’t guide anyone either to Paradise or Hell as He taught the Criterion Adhikr to everyone from the Paradise itself as told in verses 55: 1-4. See explanation 2: 256 and 10: 108.
