And Allah does not speak to any human except as inspiration, or from behind a curtain, or by sending a Messenger; thus, with His Permission, He reveals what He intends. Indeed, He is the Supreme, the Wise.
This verse says that Allah will not speak to anyone from this world, nor will anyone see Allah directly from this world, as explained in verses 6: 102-103. Allah spoke to Moses from behind a curtain. “Qudsi Hadith” is the Message of Allah inspired to the Messenger directly without the Angel. It is told in verses 21: 24-25 that the Book given to all 313 Messengers is Adhikr, which is the Truth and Proof. Adhikr revealed to the Messenger Muhammad contains all 312 Books revealed before and their upright explanations, as explained in verse 16: 44. And it is revealed through the Angel Jibreel as explained in verse 2: 1. Adhikr, which explains everything as explained in verse 16: 89, and which is the Best Interpretation of the Lord’s Book as explained in verse 25: 33, is codified through the Three-Time Knower mentioned in verse 25: 59. See explanation 7: 143.
