The Forgiver
مِثْلَ دَأْبِ قَوْمِ نُوحٍ وَعَادٍ وَثَمُودَ وَٱلَّذِينَ مِنۢ بَعْدِهِمْ ۚ وَمَا ٱللَّهُ يُرِيدُ ظُلْمًا لِّلْعِبَادِ
Like the custom of the people of Noah and of 'Aad and Thamud and those after them. And Allah wants no injustice for [His] servants.

يَـٰقَوْمِ لَكُمُ ٱلْمُلْكُ ٱلْيَوْمَ ظَـٰهِرِينَ فِى ٱلْأَرْضِ فَمَن يَنصُرُنَا مِنۢ بَأْسِ ٱللَّهِ إِن جَآءَنَا ۚ قَالَ فِرْعَوْنُ مَآ أُرِيكُمْ إِلَّا مَآ أَرَىٰ وَمَآ أَهْدِيكُمْ إِلَّا سَبِيلَ ٱلرَّشَادِ
O my people, sovereignty is yours today, [your being] dominant in the land. But who would protect us from the punishment of Allah if it came to us?" Pharaoh said, "I do not show you except what I see, and I do not guide you except to the way of right conduct."
وَقَالَ ٱلَّذِىٓ ءَامَنَ يَـٰقَوْمِ إِنِّىٓ أَخَافُ عَلَيْكُم مِّثْلَ يَوْمِ ٱلْأَحْزَابِ
And he who believed said, "O my people, indeed I fear for you [a fate] like the day of the companies -
وَيَـٰقَوْمِ إِنِّىٓ أَخَافُ عَلَيْكُمْ يَوْمَ ٱلتَّنَادِ
And O my people, indeed I fear for you the Day of Calling -
يَوْمَ تُوَلُّونَ مُدْبِرِينَ مَا لَكُم مِّنَ ٱللَّهِ مِنْ عَاصِمٍ ۗ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ
The Day you will turn your backs fleeing; there is not for you from Allah any protector. And whoever Allah leaves astray - there is not for him any guide.
