“Once abu al-Hassan (a.s.), was with a man near the grave of the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause. He looked at him (the Imam) and found his hands had the color of henna on them. Certain ones of the people of al-Madinah said, ‘Look at him. His hands are colored with henna.’ He (the Imam) turned to him and said, ‘In henna there is what you know as well as what you do not know.’ He (the Imam) then said, ‘If one after applying lime paste rubs henna all over his body, he gains immunity from three things, namely, insanity, leprosy and albinism.’”
