H 171 - Saad bin Abdullah Ashari has narrated from Abu Hashim Dawood bin Qasim Ja’fari that he said: I was with Imam Hasan Askari عليه السلام when permission for entry was sought for a Yemenite gentleman. When he entered, we saw that he was tall and he greeted the Imam as the owner of authority. I said to myself: If I only knew who this man is! Imam عليه السلام said: He is the descendant of the Bedouin lady who possessed the pebble on which my ancestors had placed their seals. After that the Imam عليه السلام said: Show that pebble, and he brought it out. The Imam placed his seal on the part, which was empty. As if we can still read the seal of the Imam and print of His Eminence that he had written: Hasan bin Ali. After that the man arose and said: Peace and blessings of Allah be on you, O Ahle Bayt عليه السلام; progeny in which some have emerged from others. I testify that your right, like the right of Amirul Momineen عليه السلام and the Holy Imams عليه السلام is obligatory; wisdom and Wilayat ends at you. You are the Wali (divine saint) of God and no one can offer any excuse of ignorance about you. I asked him what his name was; and he replied: My name is Mahja bin Salat bin Uqbah bin Samaan bin Ghanam bin Umme Ghanam. And she is the Bedouin lady from Yemen, owner of the pebble for whom Amirul Momineen عليه السلام placed his seal (on the pebble).
