I went to visit Abal Ḥasan, ‘Ali ibn Muḥammad (Imam Hādi (a.s.)), when he was ill and suffering from fever. The Imam (a.s.) said to me, “O Abā Hāshim! Send a man from among our followers to the Ḥā`ir to pray for me (to be cured).” When I left the Imam (a.s.), I met ‘Ali ibn Bilāl and I informed him of the Imam’s order and asked him to be the one to go to the Ḥā`ir. He replied, “I am at his command. However, the Imam (a.s.) is more sacred than the Ḥā`ir because he has the same rank as the one in the Ḥā`ir and it is more effective if he prays for himself than if I pray for him in the Ḥā`ir.” I informed the Imam (a.s.) about that which ‘Ali ibn Bilāl had said. The Imam (a.s.) said to me: Tell him that the Messenger of Allāh (s.a.a.w.) is more sacred than the House (of Allāh) and the Ḥajar but he used to circulate the House (of Allāh) and touch the Ḥajar. Verily, there are places in which Allāh, the Exalted, loves to be called upon and He answers the call of those who call upon Him (in those places), and the Ḥā`ir is one of those places.
