And to purge Lord Allah those who believed and to deprive the disbelievers.
At the time of Messenger, in the Battle of Badr victory was with the Messenger and followers. But in the Battle of Uhud at a glance, the followers were defeated. Then the wrongdoing hypocrites were thinking that if the Messenger and followers were in Truth, how did they fail. Being a reply to this, the Three-Time-Knower Lord says through these verses that the purpose of war is to distinguish the believers from the hypocrites. And it was also for giving the true believers a chance for martyrdom. It is told in verses 3: 166-167: ‘The Uhud Battle’ was happened to distinguish the believers and hypocrites among the followers of Messenger.
Today, the Arabic Quran reading Fujjar who hide and reject Adhikr are falsely claiming that they are in Truth. But they are in forefront of all mischievous activities all over the world. Because of that, they are facing humiliation and are being hated by other people belonging to Messenger’s community. It is told in verses 6: 89-90: “If the Fujjar didn’t utilize Adhikr, it will be entrusted to the other people belonging to Messenger’s community who will not do so”. Thus, Lord’s Word has been completed with Truth and Justice that the Fujjar will have disgrace in this world and heinous punishment in the Hereafter as explained in verses 2: 85 and 6: 115-116. See explanation 2: 39 and 3: 112.
