Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa and A number of our people have narrated from Sahl ibn Ziyad all from ibn Mahbub from Ali ibn Ri’ab from abu Basir who has said the following: “I heard Abu ‘Abdillah (a.s.) say, ‘The believer is the brother (in belief) of the believer. They are like the same body. If one part complains of pain the rest of the body also feels it. Their spirits are from one spirit.

The spirit of the believer’s connection with the spirit of Allah is stronger than the connection of the sun’s rays to the sun.’” راتب الصحة - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (9/12))
