Oh you who believed! You heed Allah and you believe in His Messenger, He will give you two fold from His Mercy, and He will give you a Light for living you with It, and he will forgive for you, and Allah is oft forgiving, the Merciful.
The Light and the Mercy mentioned in the verse is Adhikr. During the period of Messenger Muhammed Lord’s Book was not codified. So it is told in this verse that if you are keeping Allah in your heart and are believing in His Messenger, you will be given a light to live in the Straight path.
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 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: 99-100. See explanation 2: 2-5; 3: 112; 9: 71-72; and 36: 10-11.
