Surah: 082 Al-Infitar
This is a Makki Surah, and derives its name from the reference to the breaking up of the skies, at the beginning of the surah.
Describing the various events on the Day of Resurrection, such as the breaking up of the skies, falling of the stars, eruption of the oceans, among others, it is said that on that day every soul will know what it is being called to account for. The records are being kept by angels, who are noble scribes and know what each person does.
No soul will be able to assist another on the Day of Reckoning, and authority will belong to Allaah (SWT) alone.
