Oh those who believed! You give response to Lord Allah and His Messenger whenever he called you to anything that will give your life; And you know that indeed Allah is in between the person and his heart; surely, unto Him you all will be summoned.
The aim of life is to identify Allah as submitted by Adhikr—the Best Interpretation of Lord’s Book. For every creature, the Spirit—life + soul—is from the Lord itself. The peculiarity of mankind is that they are endowed with intelligence. In each man, there is a Jinn-soulmate as told in verse 43: 36-39. The believer who holdfasts Adhikr will convert his soulmate into a believer will keep Lord in his heart and will remember Lord always so that Allah will remember him back as explained in verse 2: 152. The believer will only die as Muslim—those who submit wholly to the Lord—as explained in verse 3: 102. At the time of death, the soulless and worthless hypocrites and their blind followers will witness against their soul that indeed, they were disbelievers vide verse 7: 37 and so on the Day of Judgment vide verse 6: 130. Each group among them is destined into the 7 doors of Hell as told in verse 15: 44. See explanation 2: 186, 255-257 and 4: 1-2.
