36:45
وَإِذَا قِيلَ لَهُمُ ٱتَّقُوا۟ مَا بَيْنَ أَيْدِيكُمْ وَمَا خَلْفَكُمْ لَعَلَّكُمْ تُرْحَمُونَ
wa-idhā qīla lahumu ittaqū mā bayna aydīkum wamā khalfakum laʿallakum tur'ḥamūna
Yet when they are told, ‘Beware of what lies before and behind you, so that you may be given mercy,’
And when it is said to them: "Fear of that which is before you (worldly torments), and that which is behind you (torments in the Hereafter), in order that you may receive Mercy (i.e. if you believe in Allâh’s religion - Islâmic Monotheism, and avoid polytheism, and obey Allâh with righteous deeds)."
