11. Sahl ibn Ziyad has narrated from Yahya ibn al-Mubarak from ‘Abd Allah ibn Jabalah from Ishaq ibn ‘Ammar from Abu ‘Abdillah (a.s.) who has said the following
“There had never been, there is no one and will never be a believer but that a neighbor causes him suffering. Even if a believer may live on an island Allah sends someone to cause him suffering.”
