(Al-Ahraf) 7 : 157
الَّذِينَ يَتَّبِعُونَ الرَّسُولَ النَّبِيَّ الْأُمِّيَّ الَّذِي يَجِدُونَهُ مَكْتُوبًا عِنْدَهُمْ فِي التَّوْرَاةِ وَالْإِنْجِيلِ يَأْمُرُهُمْ بِالْمَعْرُوفِ وَيَنْهَاهُمْ عَنِ الْمُنْكَرِ وَيُحِلُّ لَهُمُ الطَّيِّبَاتِ وَيُحَرِّمُ عَلَيْهِمُ الْخَبَائِثَ وَيَضَعُ عَنْهُمْ إِصْرَهُمْ وَالْأَغْلَالَ الَّتِي كَانَتْ عَلَيْهِمْ ۚ فَالَّذِينَ آمَنُوا بِهِ وَعَزَّرُوهُ وَنَصَرُوهُ وَاتَّبَعُوا النُّورَ الَّذِي أُنْزِلَ مَعَهُ ۙ أُولَٰئِكَ هُمُ الْمُفْلِحُونَ

Those who are following the Messenger, the illiterate Prophet about whom they can find written down in ‘Tourath’ and ‘Injeel’ with them, he commands them with the Justice and forbids them about the evils, and he permits for them the wholesome things and prohibits upon them the impure, and he unloads from them their burdens and shackles which had been tied upon them. So those who believe in him, strengthen him, help him, and are following the Light sent down with him, such are only prosperous.

It is told in verses 36: 8-10 about the Meccan pagans before deputing Messenger Muhammed: "Indeed, Lord has put shackles on their necks reaching to their chins, so they are with heads aloft. And Lord has put before them a barrier and behind them a barrier and covered them, so they don't see". That means the life of Meccan pagans was so dark that there was no peace and tranquility.

The illiterate Messenger or Prophet mentioned in this verse is Muhammad who was deputed to the Meccan pagans. Adhikr sent down to Messenger Muhammad contains all previous 312 Books and their Upright Explanations as explained in verse 16: 44. 

But after thirty years of the last Messenger's departure, his people by hiding and rejecting Adhikr have become the Arabic Quran reading Fujjar. They have become the true disbelievers mentioned in verses 4: 150-151. Hypocrites among them have converted the Favor Adhikr into disbelief and made permissible Hell (the house of worthless) to their followers as explained in verses 14: 28-29. The Fujjar are not following any of the Messenger or Prophet, instead, they are following books written by 29 pseudo-prophets and hypocrites. They are denoted as the worst creatures who are not utilizing their intelligence in verse 8: 22. It is told in verse 6: 89 that if the people of Messenger hide and reject Adhikr, the Lord will entrust It to other people belonging to Messenger's community who will not do so. The Fujjar who accept Antichrist first as a prophet and later as the lord will be killed by the other people who will accept Adhikr and Islam as explained in verses 4: 91; 5: 33; 9: 5, 123, and 33: 60-61. At that time only the Fujjar will accept that not Arabic Quran but Adhikr or Dhikree was Lord's Book as told in verse 38: 8.

Only one in a thousand becomes a believer who testifies Adhikr. He follows a lifestyle as explained in verses 7: 205-206. See explanation 2: 5; 4: 174-175; 5: 15-16, and 54.
