Sahih al-Bukhari 4933
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.‏
