Tafsir Ibn Kathir -> Surah Al-Aadiyaat -> The Threat about the Hereafter

Then Allah encourages abstinence from worldly things and striving for the Hereafter, and He informs of what the situation will be after this present condition, and what man will face of horrors. He says,

﴿أَفَلاَ يَعْلَمُ إِذَا بُعْثِرَ مَا فِى الْقُبُورِ ﴾

(Knows he not that when the contents of the graves are poured forth) meaning, the dead that are in it will be brought out.

﴿وَحُصِّلَ مَا فِى الصُّدُورِ ﴾

(And that which is in the breasts shall be made known) Ibn `Abbas and others have said, "This means what was in their souls would be exposed and made apparent.''

﴿إِنَّ رَبَّهُم بِهِمْ يَوْمَئِذٍ لَّخَبِيرٌ ﴾

(Verily, that Day their Lord will be Well-Acquainted with them.) meaning, He knows all of that they used to do, and He will compensate them for it with the most deserving reward. He does not do even the slightest amount of injustice. This is the end of the Tafsir of Surat Al-`Adiyat, and all praise and thanks are due to Allah.
