It is nothing except the names you and your forefathers named, for which Allah hasn’t sent down any Authority about them; indeed, they are not following anything except conjectures and their souls’ whims, while surely the Guidance from their Lord has come to them.
Even though Adhikr, which is the Guidance from the Lord of the universe, has come to them through their honest companion, they were only following their whims and guessing. What they had been serving was only some names which they and their forefathers had been naming, and Allah had not sent any authority for them. The different organisations among the Arabic Qur'an Reading Fujjar as explained in verses 30: 30-32 and 58: 19 are also formed by the conjectures and whims of Fujjar after thirty years of Messenger's departure for which they have no any evidence from Lord's Book Adhikr. See explanation 58: 22.
The disbelievers during the period of Messenger Muhammad were demanding a codified Book Adhikr. Today Adhikr, which is the Best Interpretation of the Lord’s Book mentioned in verses 25: 33-34, is codified as a Book. But the Arabic Qur’an Reading Fujjar, who are mentioned as worthless people in verses 25: 18 and 48: 12, and who have made their food rejecting Adhikr as told in verse 56: 82, are hastening for the end of the world by not utilizing It themselves and not giving It to be utilized by others as explained in verse 6: 26. See explanation 34: 19-20; 45: 23-24; and 46: 34-35.
