Narrated Ibn `Abbas: (as regards the explanation of Hadith 454). 'Indeed, it (Hell) throws about sparks (huge) as Forts.' We used to collect wood in the form of logs, three cubits long or shorter. for heating purposes in winter., and we used to call such wood, the Qasr.

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، أَخْبَرَنَا سُفْيَانُ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَابِسٍ، قَالَ سَمِعْتُ ابْنَ عَبَّاسٍ، إِنَّهَا تَرْمِي بِشَرَرٍ كَالْقَصْرِ قَالَ كُنَّا نَرْفَعُ الْخَشَبَ بِقَصَرٍ ثَلاَثَةَ أَذْرُعٍ أَوْ أَقَلَّ، فَنَرْفَعُهُ لِلشِّتَاءِ فَنُسَمِّيهِ الْقَصَرَ‏.‏

Narrated Ibn 'Abbas: (regarding) the explanation of "... It throws sparks as Al-Qasr..." (V. 77:32): We used to collect logs of wood, three cubits long or longer, to store for heating purposes in winter, and we used to call it Al- Qasr, it also means a castle or a fort. "As if they were Jimalatun Sufr (yellow camels or bundles of ropes)" (V.77:33): means the ropes of a ship which are made in bundles till it become as wide as men's waists.

حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ، حَدَّثَنَا يَحْيَى، أَخْبَرَنَا سُفْيَانُ، حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ عَابِسٍ، سَمِعْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ ‏{‏تَرْمِي بِشَرَرٍ‏}‏ كُنَّا نَعْمِدُ إِلَى الْخَشَبَةِ ثَلاَثَةَ أَذْرُعٍ وَفَوْقَ ذَلِكَ، فَنَرْفَعُهُ لِلشِّتَاءِ فَنُسَمِّيهِ الْقَصَرَ‏.‏ ‏{‏كَأَنَّهُ جِمَالاَتٌ صُفْرٌ‏}‏ حِبَالُ السُّفْنِ تُجْمَعُ حَتَّى تَكُونَ كَأَوْسَاطِ الرِّجَالِ‏.‏
