72:1-2
قُلْ أُوحِيَ إِلَيَّ أَنَّهُ اسْتَمَعَ نَفَرٌ مِّنَ الْجِنِّ فَقَالُوا إِنَّا سَمِعْنَا قُرْآنًا عَجَبًا يَهْدِي إِلَى الرُّشْدِ فَآمَنَّا بِهِ
“Say: It has been revealed to me that a group of jinn listened and said: Indeed we have heard a wondrous Quran. It guides to right conduct, and we have believed in it.”
The jinn's spontaneous recognition of the Quran's wonder and guidance – without the benefit of seeing miracles or meeting the Prophet – illustrates the Quran's innate power to convince pure hearts.
72:26
عَالِمُ الْغَيْبِ فَلَا يُظْهِرُ عَلَىٰ غَيْبِهِ أَحَدًا
“He is the Knower of the unseen, and He does not disclose His knowledge of the unseen to anyone.”
A definitive statement on the monopoly of divine knowledge – the unseen belongs exclusively to Allah, closing any claim to occult knowledge by jinn, soothsayers, or any other being.
