(Ambiya') 21 : 24
أَمِ اتَّخَذُوا مِنْ دُونِهِ آلِهَةً ۖ قُلْ هَاتُوا بُرْهَانَكُمْ ۖ هَٰذَا ذِكْرُ مَنْ مَعِيَ وَذِكْرُ مَنْ قَبْلِي ۗ بَلْ أَكْثَرُهُمْ لَا يَعْلَمُونَ الْحَقَّ ۖ فَهُمْ مُعْرِضُونَ
Or they have chosen deities besides Him? You say: "Bring your Proof. This is the Reminder for those with me and the Reminder of those before me"; but most of them are not knowing the Truth, then they are neglecting It.
The Proof, Reminder, and Truth mentioned in this verse is Adhikr which is sent down to all 313 Messengers from time to time. And Adhikr sent down to Messenger Muhammad contains all 312 previous Books and their Upright explanations. Today, Adhikr is codified as the Best Interpretation of Lord’s Book through the Three-Time-Knower mentioned in verse 25: 59. But Arabic Quran reading Fujjar who hide and reject Adhikr are into Hell as explained in verse 4: 118. See explanation 2: 119; 11: 118-119 and 16: 43-44.
