(Ar-Ra'd) 13 : 27
وَيَقُولُ الَّذِينَ كَفَرُوا لَوْلَا أُنْزِلَ عَلَيْهِ آيَةٌ مِنْ رَبِّهِ ۗ قُلْ إِنَّ اللَّهَ يُضِلُّ مَنْ يَشَاءُ وَيَهْدِي إِلَيْهِ مَنْ أَنَابَ
And those who disbelieved asked: "Why a sign has not been sent down upon him from his Lord?" You say: "Indeed, Allah strays whom He Wishes and guides whoever turns into Him.
The Impartial Lord has taught Adhikr to each soul from the Paradise itself. He will never guide or stray anyone as explained in verse 7: 178. Those who testify Adhikr as the Guidance, Mercy, and Herald are the true Muslims (those who submit wholly to Lord) as explained in verse 11: 109. So, whoever holdfasts Adhikr, he did holdfast Lord and is guided into the Straightpath as explained in verses 3: 101-102 and 4: 174-175. See explanation 4: 78-79; 10: 108-109 and 11: 118-119.
