Divine punishment and mercy

ثُمَّ بَعَثْنَـٰكُم مِّنۢ بَعْدِ مَوْتِكُمْ لَعَلَّكُمْ تَشْكُرُونَ

Then We revived you after your death that perhaps you would be grateful.

وَلَقَدْ أَخَذْنَآ ءَالَ فِرْعَوْنَ بِٱلسِّنِينَ وَنَقْصٍ مِّنَ ٱلثَّمَرَٰتِ لَعَلَّهُمْ يَذَّكَّرُونَ

And We certainly seized the people of Pharaoh with years of famine and a deficiency in fruits that perhaps they would be reminded.

وَلَمَّا وَقَعَ عَلَيْهِمُ ٱلرِّجْزُ قَالُوا۟ يَـٰمُوسَى ٱدْعُ لَنَا رَبَّكَ بِمَا عَهِدَ عِندَكَ ۖ لَئِن كَشَفْتَ عَنَّا ٱلرِّجْزَ لَنُؤْمِنَنَّ لَكَ وَلَنُرْسِلَنَّ مَعَكَ بَنِىٓ إِسْرَٰٓءِيلَ

And when the punishment descended upon them, they said, "O Moses, invoke for us your Lord by what He has promised you. If you [can] remove the punishment from us, we will surely believe you, and we will send with you the Children of Israel."

قَيِّمًا لِّيُنذِرَ بَأْسًا شَدِيدًا مِّن لَّدُنْهُ وَيُبَشِّرَ ٱلْمُؤْمِنِينَ ٱلَّذِينَ يَعْمَلُونَ ٱلصَّـٰلِحَـٰتِ أَنَّ لَهُمْ أَجْرًا حَسَنًا

[He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward [i.e., Paradise].

فَلَمَّا كَشَفْنَا عَنْهُمُ ٱلْعَذَابَ إِذَا هُمْ يَنكُثُونَ

But when We removed from them the affliction, at once they broke their word.
