Imam Reza (as) - Generosity 1

Ahmed b. ‘Ubayd Allāh on the authority of al-Ghaffāri, who said: “A man from the family of Abū Rāfi‘, the retainer of the Apostle of Allah, may Allah bless him and his family, called so- and-so, had me in his debt. He demanded payment from me and insisted on my paying him. When I realized that, I prayed the morning prayer in the mosque of the Apostle of Allah, may Allah bless him and his family, and I set out to see al-Ridā, peace be on him. On that day, he was in the valley of al-‘Arid. When I got near his door, he came out. He was wearing a shirt and a clock (ridā’). When I looked at him, I felt ashamed before him. When he reached me, he stood and looked at me. I greeted him ¾it was the month of Ramadān. I said: ‘May I be your ransom, your retainer so-and-so has me in his debt. By Allah, he has spread reports of me around.’
“By Allah, I was thinking to myself, that he would tell him to leave me alone. By Allah, I had not told him how much I owed nor had I given specific details about anything. He told me to sit down until he came back. I was still there at the time when I prayed the sunset prayer. I had been fasting and I had become troubled and wanted to leave. Suddenly, he came. There was (a crowd of) people.
“Beggars were begging from him and he was giving them alms. Then he retired from them and went into his house. He came out and called me. I rose and went in with him. He sat down and I sat down with him. I began to talk to him about the governor of Medina. When I had finished, he said to me: ‘I do not think that you have eaten yet?’ ‘Yes,’ I replied.
“He called for food for me and it was put in front of me. He told the servant to eat with me. The servant and I had our fill of food. When we had finished, he said: ‘Raise the cushion and take what is under it.
“I raised it and there was (many) dinars. I took them and put them in my sleeve. He told some of his servants to accompany me to my house, and they did. I went to my house and called for a lamp. I examined the dinars and they were forty-eight dinars. I only owed the man twenty-eighty dinars. On a dinar of them it was engraved: ‘The debt to the man is twenty-eighty dinars and the rest is yours.’ ( Al-Majjlisi, Bihār al-Anwār, vol. 12,  p. 28. )
