وَإِذْ فَرَقْنَا بِكُمُ ٱلْبَحْرَ فَأَنجَيْنَـٰكُمْ وَأَغْرَقْنَآ ءَالَ فِرْعَوْنَ وَأَنتُمْ تَنظُرُونَ
And [recall] when We parted the sea for you and saved you and drowned the people of Pharaoh while you were looking on.

وَٱتَّقُوا۟ يَوْمًا لَّا تَجْزِى نَفْسٌ عَن نَّفْسٍ شَيْـًٔا وَلَا يُقْبَلُ مِنْهَا شَفَـٰعَةٌ وَلَا يُؤْخَذُ مِنْهَا عَدْلٌ وَلَا هُمْ يُنصَرُونَ
And fear a Day when no soul will suffice for another soul at all, nor will intercession be accepted from it, nor will compensation be taken from it, nor will they be aided.
وَإِذْ نَجَّيْنَـٰكُم مِّنْ ءَالِ فِرْعَوْنَ يَسُومُونَكُمْ سُوٓءَ ٱلْعَذَابِ يُذَبِّحُونَ أَبْنَآءَكُمْ وَيَسْتَحْيُونَ نِسَآءَكُمْ ۚ وَفِى ذَٰلِكُم بَلَآءٌ مِّن رَّبِّكُمْ عَظِيمٌ
And [recall] when We saved your forefathers from the people of Pharaoh, who afflicted you with the worst torment, slaughtering your [newborn] sons and keeping your females alive. And in that was a great trial from your Lord.
وَإِذْ وَٰعَدْنَا مُوسَىٰٓ أَرْبَعِينَ لَيْلَةً ثُمَّ ٱتَّخَذْتُمُ ٱلْعِجْلَ مِنۢ بَعْدِهِۦ وَأَنتُمْ ظَـٰلِمُونَ
And [recall] when We made an appointment with Moses for forty nights. Then you took [for worship] the calf after him, while you were wrongdoers.
ثُمَّ عَفَوْنَا عَنكُم مِّنۢ بَعْدِ ذَٰلِكَ لَعَلَّكُمْ تَشْكُرُونَ
Then We forgave you after that so perhaps you would be grateful.
