Arabic text
غَافِرِ ٱلذَّنۢبِ وَقَابِلِ ٱلتَّوْبِ شَدِيدِ ٱلْعِقَابِ ذِى ٱلطَّوْلِ ۖ لَآ إِلَـٰهَ إِلَّا هُوَ ۖ إِلَيْهِ ٱلْمَصِيرُ
Translation
(Allaah is also) The Forgiver of sins, Acceptor of repentance, Severe (quick and firm) in punishment, and All Powerful. There is no Ilaah but Him, and all (creation) shall return to Him (after death for judgement).
