Islam is the only way of life satisfied by the Creator Lord for his entire creatures as explained in verse 3: 19. Since there is no compulsion in the true way of life, nobody can make anyone a believer. So it is the responsibility of every individual who has attained 15th age to reform their character under the Light of Adhikr and to become a believer. The Arabic Quran reading Fujjar who doesn’t do so, they are the disbelievers into Hell as explained in verse 15: 44. It is the inevitable responsibility of parents to guide their children with Adhikr before attaining their 15th age. See explanation 2: 62; 4: 150-151 and 28: 57.
