Oh, you who believed! You heed Allah, and you believe in His Messenger; He will give you twofold from His Mercy, and He will give you a Light for you to live with It, and He will forgive you, and Allah is Oft-Forgiving, the Merciful.
The Light and the Mercy mentioned in the verse are Adhikr. During the period of Messenger Muhammad, the Lord’s Book was not codified. So it is told in this verse that if you are keeping Allah in your heart and believe in His Messenger, you will be given a Light to live in the Straightpath.
But today the Fujjar who are reading these verses by forgetting Adhikr have become worthless, as explained in verses 25: 17-18. These worst creatures among thousand communities of the Lord’s creatures, as told in verse 8: 22, instead of getting forgiveness will get punishment for destroying the universe, as explained in verses 6: 26 and 20: 99-101. See explanation 2: 2-5; 3: 112; 9: 71-72; and 36: 10-11.
