Al-Mursalat 77:30

Allah said,</p><div class="arabic uthmani">إِنَّهَا تَرْمِى بِشَرَرٍ كَالْقَصْرِ </div><p>(Verily, it throws sparks as Al-Qasr,) meaning, its sparks will shoot out from its flame like huge castles. Ibn Mas`ud said, "Like forts." Ibn `Abbas, Mujahid, Qatadah and Malik who reported from Zayd bin Aslam and others …

"Depart ye to a Shadow (of smoke ascending) in three columns,

"Depart you to a shadow (of Hell-fire smoke ascending) in three columns,

“Proceed to a shadow of three different masses.”
