Inna as-haba aljannati alyawma fee shughulin fakihoon (surah Yasin: 55)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(36:55) Indeed, the people of Paradise will be busy enjoying themselves: *51

Inna Ashaabal jannatil Yawma fee shughulin faakihoon

*51) To understand this one should remember that the righteous believers will not be withheld in the Plain of Resurrection, but in the very beginning they will be sent to Paradise without accountability, or after a mild reckoning, because their record will be clean. There will be no need to keep them waiting during the hearing by the Court. Therefore, Allah will tell the culprits, who will be required to render their accounts, in the Plain of Resurrection: "Look ! the righteous people whom you used to mock and regard as foolish in the world, are today enjoying the pleasures of Paradise because of their wisdom, and you, who in your own judgement were very prudent and sagacious, are being condemned to accountability for your misdeeds."
