Ar-Rayyan bin as-Salt

Al-Kashshi mentioned that Ma’mar bin Khallad said, ‘Ar-Rayyan bin as-Salt, when al-Fadhl bin Sahl wanted to send him to one of the districts of Khurasan, said to me, ‘I want you to ask permission for me to come in to Abul Hasan (peace be on him) to greet and farewell him. I like him to give me from his clothes and some dirhams that have been coined with his name.’ When I went to him (to Imam al-Hadi), he immediately said to me, ‘O Ma’mar, Where is Rayyan? Does he like to come to us so that I give him from my clothes and from my dirhams?’ I said, ‘Glory be to Allah! By Allah, he just asked me to ask you for that.’ He said, ‘O Ma’mar, the faithful are successful. Ask him to come!’ I asked him to come in and he did. He greeted Imam al-Hadi (a.s.), who gave him one of his garments. When he came out, I found thirty dirhams in his hand.’ ( Rijal al-Kashshi.)
