(Swaad) 38 : 66
رَبُّ السَّمَاوَاتِ وَالْأَرْضِ وَمَا بَيْنَهُمَا الْعَزِيزُ الْغَفَّارُ

The Lord of heavens, earth, and all things in between both of them; the Exalted, the Forgiver.

Lord of all living things as well as nonliving things including mankind is the Exalted and the unquestionable. He forgives sins and offenses done before due to ignorance if it is confessed to Him as it should be. See explanation 25: 58-59, 67-70; 32: 4, and 39: 53-55.
