What will happen on the Day of Judgement, and that is the rolling up of the Sun
Ali bin Abi Talhah reported from Ibn Abbas;
إِذَا الشَّمْسُ كُوِّرَتْ
When the sun is Kuwwirat.
"This means it will be darkened."
Al-`Awfi reported from Ibn Abbas; "It will go away."
Qatadah said, "Its light will go away."
Sa`id bin Jubayr said, "Kuwwirat means it will sink in."
Abu Salih said, "Kuwwirat means it will be thrown down."
At-Takwir means to gather one part of something with another part of it (i.e., folding). From it comes the folding of the turban (Imamah) and the folding of clothes together.
Thus, the meaning of Allah's statement,
كُوِّرَتْ
(Kuwwirat) is that part of it will be folded up into another part of it. Then it will be rolled up and thrown away. When this is done to it, its light will go away.
Al-Bukhari recorded from Abu Hurayrah that the Prophet said,
الشَّمْسُ وَالْقَمَرُ يُكَوَّرَانِ يَوْمَ الْقِيَامَة
The sun and the moon will be rolled up on the Day of Judgement.
Al-Bukhari was alone in recording this Hadith and this is his wording of it.
Dispersing the Stars
وَإِذَا النُّجُومُ انكَدَرَتْ
