Oh those who believed, give your 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.
