“I was in Madina when the roof over the grave of the Holy Prophet (s.a) had crumbled down and the workers were climbing up and down (for repairs). We were a group and said to our people, “Who has an appointment with abu ‘Abdallah (a.s.)?” Mihran ibn abu Nasr said, “I have an appointment with the Imam (a.s.).” ’Isma‘il ibn ‘Ammar al-Sayrafi said, “I have an appointment with the Imam (a.s.).” I said to them, “Ask the Imam (a.s.) if it is permissible to climb up and look on to the grave of the Holy Prophet (s.a).” Next day we met them and we all came together. ’Isma‘il said, “We asked your question and he said this. “I do not like anyone to climb over him and I do not feel safe for anyone whose eye sight may go away because of catching sight of something that cause him such loss or see him standing in prayer or see him with anyone of his wives.”
