Oh, you who believed! You heed Lord Allah with the Truth as it should be, and you shouldn’t die except you are submitted wholly to Lord Allah.
Adhikr is the Safeguard against all disasters, diseases, and Hellfire. No one becomes a believer without changing his Jinn soulmate mentioned in verses 43: 36-39 into a believer with the Truth Adhikr. Only by doing so, one can keep Lord in his heart. The one who keeps Lord in his heart with Adhikr will not be hurt or killed by anyone or by any accident. So, the believer who follows the Best Book Adhikr can die peacefully and tranquility by submitting wholly to his Lord as told in verses 9: 100; 89: 27-30, and 98: 7-8. Adhikr is the Guidance, Mercy, and Herald for the true Muslims who submitted wholly to Lord as told in verse 16: 89. Lord has taught through his Messenger: “None of you becomes a believer unless his whim follows Adhikr”
It is the duty of those who received the Book to teach their offspring Adhikr before their fifteenth age. The Fujjar will die by witnessing against their soul that indeed, they were disbelievers as explained in verse 10: 60. The disbelieving parents and offspring will quarrel with each other in Hell as told in verses 7: 38-39. The Fujjar are destined into the seven doors of Hell as told in verse 15: 44. Verses 2: 278; 5: 35; 33: 70; 57: 28 and 59: 18 start by saying: “Oh you who believed! You heed Lord Allah”. See explanation 2: 152 and 4: 150-151.
