And they say: "We have believed in Allah and the Messenger, and we obeyed", then a group among them turns away after that, and those are not believers.
The character of hypocrites during the time of Messenger is described in this verse. 30 years after the Messenger’s departure, the Arabic Quran reading Fujjar has worse character than the hypocrites of all time. They claim that they are Muslims, but by hiding and rejecting Adhikr they are the Mujirims serving Satan as explained in verse 16: 89. The read, heard, and touched verses will argue and witness against these disbelievers and will push them into Hell as explained in verse 7: 40. These disbelieving and wrongdoing Fujjar will blame, argue and curse each other in Hell as explained in verses 2: 165-167. See explanation 9: 67-68 and 22: 53-55.
