When the sun is wrapped up [in darkness] (81:1)

Almuntakhab Fi Tafsir Alquran Alkarim

When once the sun is contracted and loses light and becomes dim

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

(81:1) When the sun shall be folded up, *1

When the sun is wrapped up [in darkness] meaning

*1) This is a matchless metaphor for causing the sun to lose its light. Takwir means to fold up; hence takwir al- `amamah for folding up the turban on the head. Here, the light which radiates from the sun and spreads throughout the solar system has been likened to the turban and it has been said that on the Resurrection Day the turban will be folded up about the sun and its radiation will fade.
