O Harthama!
O Harthama! Do not do anything related to my ceremonial burial ablutions until you see a white tent set up next to the house. Once you see it set up, take me inside wearing the clothes which I had died. Stay outside and wait along with the others. Do not raise the tent to look in, lest you will be destroyed. Then Al-Ma’mun will come to you and ask, ‘O Harthama! Don’t you say that no one but a Divine Leader can wash a Divine Leader’s body?
Then who washed Abal Hassan Ali ibn Musa (a.s.) while his son Muhammad (a.s.) was in Medina that is one of the cities in Hijaz, and Ar-Ridha’ (a.s.) is here in Toos?’ Once Al-Ma’mun says this, you should answer him as follows, ‘No one needs to perform the ceremonial burial ablutions for a Divine Leader, except for the Divine Leader after him.
