1. Abu Ali al-Ash’ari has narrated from al-Hassan ibn Ali al-Kufi from ‘Ubays ibn Hisham from al-Husayn ibn Ahmad al-Minqari from Yunus ibn Zabyan from Abu ‘Abdillah (a.s.) who has said the following
“In you there is a light by which you are identified in this world. It is as such that even when one of you meets his brother (in belief) he kisses him at the place of light in his forehead.”
