8ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ قَالَ رَسُولُ الله (صَلَّى اللهُ عَلَيْهِ وآلِه) يَنْبَغِي لِلْجُلَسَاءِ فِي الصَّيْفِ أَنْ يَكُونَ بَيْنَ كُلِّ اثْنَيْنِ مِقْدَارُ عَظْمِ الذِّرَاعِ لِئَلا يَشُقَّ بَعْضُهُمْ عَلَى بَعْضٍ فِي الْحَرِّ.
8. Ali ibn Ibrahim has narrated from his father from al-Nawfali from al-Sakuni from Abu ‘Abdillah 
who has said the following: “The Messenger of Allah has said, ‘In a gathering during summer the distance between two people should be an elbow’s length (about eighteen inches) so that no difficulty is caused to any of them.’”
