quran:36:45 –

But when it is said to them, "Beware of what is before you and what is behind you; perhaps you will receive mercy... "  

And when it is said to them, ‘Beware of that which is before you, of the chastisement of this world, as ˹it is said˺ to others, and that which is behind you, of the chastisement of the Hereafter, that perhaps you might find mercy’, they turn away ˹in aversion˺.
القرآن:٣٦:٤٥ –

وَإِذَا قِيلَ لَهُمُ اتَّقُوا مَا بَيْنَ أَيْدِيكُمْ وَمَا خَلْفَكُمْ لَعَلَّكُمْ تُرْحَمُونَ  

{وإذا قيل لهم اتقوا ما بين أيديكم} من عذاب الدنيا كغيرهم {وما خلفكم} من عذاب الآخرة {لعلكم ترحمون} أعرضوا.
