And how can you disbelieve while Lord Allah’s verses are being explained upon you, and His Messenger is among you? And anyone who holdfasts Allah, then surely he is guided to the Straightpath.
Those who were given the Book know Messenger more than they knew about their children as explained in verse 2: 146. To holdfast the Lord means to holdfast Adhikr which is the Unbreakable Rope extended from Paradise to earth as explained in verse 2: 256. It is told in verse 4: 175: “Those who are believing with Lord and holdfast Adhikr, then He will make enter them into His Mercy and Bounty, and will guide them into the Straightpath”. It is told in verse 4: 146: “Those who repent, reform, holdfast Lord, and dedicate their whole life sincerely to Lord, those are with the believers, and surely Lord will give believers a great reward”. They can become those who enter Paradise after Trial.
For the Arabic Quran reading Fujjar who hide and reject Adhikr, Hell is promised to them as told in verse 11: 17. The hypocrites who hide Adhikr will enter the bottom of Fire, and they will not find any helpers there as told in verse 4: 145. Satan will obstruct mankind, not from the Arabic Quran, but Adhikr as told in verses 25: 27-29. So, the believer should follow a lifestyle explained in verses 7: 205-206. See explanation 3: 79-80, 86-91, and 5: 48.
