(Mu'amin) 40 : 3
غَافِرِ الذَّنْبِ وَقَابِلِ التَّوْبِ شَدِيدِ الْعِقَابِ ذِي الطَّوْلِ ۖ لَا إِلَٰهَ إِلَّا هُوَ ۖ إِلَيْهِ الْمَصِيرُ
Forgiver of offenses, Acceptor of repentance, severe in retribution, having wide influence, there is no Deity except He, to Him all are returned.
There is no one except Allah to invoke, seek help, fear, or answer for this worldly life. He alone forgives sins and offenses and accepts the repentance of His servants. This verse warns that whoever, after receiving Adhikr—the Ticket to Paradise—doesn’t utilize it, will face severe punishment. See explanation 20: 3; 39: 53-55, 63.
