(At-Thouba) 9 : 90
وَجَاءَ الْمُعَذِّرُونَ مِنَ الْأَعْرَابِ لِيُؤْذَنَ لَهُمْ وَقَعَدَ الَّذِينَ كَذَبُوا اللَّهَ وَرَسُولَهُ ۚ سَيُصِيبُ الَّذِينَ كَفَرُوا مِنْهُمْ عَذَابٌ أَلِيمٌ

And from the Bedouins came to you asking excuses in the order you to permit them, and they sat with those who told lie to Lord Allah and His Messenger; certainly, they will be afflicted with a painful punishment upon those who disbelieved among them.

During the revelation of this verse, the Book was not codified. As explained in verses 3: 7 and 10, the Arabic Qur’an reading Fajir and Kafir are the real disbelievers who are knowingly hiding and reject Adhikr and Its 40 names. They are reading in verses 25: 33-34 that whoever didn’t testify Adhikr will be dragged prone on their faces into the Hell, and such are in the worst place and they are the most strayed. 

Since Adhikr is formed as a Book today, whoever follows the paths other than that of Messengers and believers—Straightpath, he will be roasted in Hell as explained in verse 4: 115. The hypocrites who hide Lord’s Book and those who purchase petty price for Lord’s verses are filling Fire in their bellies, and thus they purchased astray instead of Guidance, and thus they are in a far schism as explained in verses 2: 174-176. The Trust Adhikr is revealed to punish the wrongful hypocrites and foolish Mushriks as explained in verse 9: 68. See explanations 1: 7; 2: 78-79, 159; 4: 56 and 140.
