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.’”
