And who believed in what has been sent down to you as well as whatever sent down before you, and they are having confirmed belief with the Hereafter.
Lord has taught through His Messenger: “Whoever follows the prohibitions of the Book as permissible, he doesn’t believe with It”. Therefore, the one who doesn’t know Adhikr doesn’t believe in the Lord's Book. Lord says repeatedly in verses 54: 17, 22, 32, and 40: “Surely We have made this Reading very easy to understand with hearts, is there anyone to receive the admonition?” Satan obstructs mankind, not from the Arabic Quran but Adhikr as explained in verse 25: 29. Belief in the previous Books can be formed only by understanding the Criterion Adhikr.
Through verse 4: 136 Lord says by calling the believers: “Oh you who believed, you believe with Lord Allah, His Messenger and the Book which He has been sent down to His Messenger as well as the Books sent down previously; anyone who disbelieves with the Lord, His Angels, His Books, His Messengers and the Last Day, he has gone far astray from the Truth”. See explanation 2: 2.
The people with confirmed belief are those who holdfast Adhikr which is the ‘Confirmed Truth’. It is told in verse 45: 20: “Adhikr is the Insight for the entire mankind, Guidance as well as Mercy for those people who have confirmed belief”. Verse 32: 12 says: “If you could see how Mujirims will bow their heads before their Lord saying: ‘Our Lord, we have observed and heard the scene of Hell; so you send us back to the earth, so that we may do good deeds; indeed we have become the confirmed believers! ”Messengers, Prophets, and believers are speaking for the sake of the Lord. When there is no such a believer anywhere in the world, the Lord will send a Monster to speak for Him as one of the Ten Crucial Signs of the Last Day as explained in verse 6: 158. It is told in verse 27: 82: “We shall bring forth a Monster out-busted from the earth which will speak to them that ‘mankind has no convinced belief with Our verses”. Here, instead of saying ‘Lord’s verses’ it is said ‘Our verses’. That means the Beast will be speaking for the sake of the Lord. See explanation 1: 3 and 27: 1-3.
