Oh those who believed! You obey Lord Allah and obey the Messenger and the authority having commanding power from among you, and if you differ in anything, then you refer it to Allah and the Messenger if you are believing with Allah and with the Last Day, that is good and having better consequence.
After thirty years of Messenger's departure, the Book reading people have become the Fajir and Kafir (Fujjar) as explained in verses 3: 7-10. They are following the books written by the twenty-nine pseudo-prophets. Instead of obeying Lord and the Messenger, they are following the footsteps of Satan as explained in verses 2: 208-210. So, these Fujjar will argue, blame, and curse each other in Hell as explained in verse 2: 165-167.
Today, Adhikr is codified as the Best Interpretation of Lord's Book through the Three-Time-Knower mentioned in verse 25: 59. It is commanded to Messenger to ask about the Impartial to the Three-Time-Knower mentioned in verse 25: 59. And anyone who has any doubt regarding any matter should ask the author of Adhikr as told in verses 16: 43 and 21: 7.
As there are no leaders who command with Adhikr anywhere in the world, the believer should holdfast Adhikr with his molar teeth as taught by Lord through His Messenger. Whoever holdfasts Adhikr, he did holdfast Lord and is guided into the Straightpath as explained in verses 3: 101 and 5: 48. The believer should follow the lifestyle explained in verses 7: 205-206. See explanation 3: 28, 31-32, and 4: 150-151.
