Surah 2. Al-Baqara
Ayah 47 - 48
47 يَـٰبَنِىٓ إِسْرَٰٓءِيلَ ٱذْكُرُوا۟ نِعْمَتِىَ ٱلَّتِىٓ أَنْعَمْتُ عَلَيْكُمْ وَأَنِّى فَضَّلْتُكُمْ عَلَى ٱلْعَـٰلَمِينَ
48 وَٱتَّقُوا۟ يَوْمًا لَّا تَجْزِى نَفْسٌ عَن نَّفْسٍ شَيْـًٔا وَلَا يُقْبَلُ مِنْهَا شَفَـٰعَةٌ وَلَا يُؤْخَذُ مِنْهَا عَدْلٌ وَلَا هُمْ يُنصَرُونَ
[47-48] O Children of Israel! Just recall to mind My favour that bestowed upon you, and remember that I exalted you above all the peoples of the world.62 And guard yourselves against the Day when no one shall avail anyone anything; nor shall intercession be accepted from anyone; nor shall anyone be acquitted for any (amount of) ransom; nor shall the guilty ones be helped from any quarter.63
62It refers to the period when the Israelites were the only people in the world who possessed the knowledge of the Truth from Allah and were, therefore, made leaders of the people of the world and were required to invite all other nations to His submission and to guide them on the Right Way.
63In this verse the Israelites have been warned to guard against their wrong notion about the Hereafter, for this was the main cause of their degeneration. They were under the delusion that they would win salvation just because they were the descendants of great Prophets and had relations with great saints and pious and righteous people. That is why they neglected we religion and involved themselves in sin. Here they are being disillusioned and warned that they will not escape the consequences of their evil deeds by virtue of their relation with some holy person or his intercession in their behalf. That is why immediately after reminding them of the favour (v. 47) they have been warned that they shall be punished like the guilty people who lived in this world without belief in the Hereafter.
