According to rahyafte (the missionaries and converts website) Ibne Sayyaba, a resident of Kufa in Iraq, was a young man whose father had died. The tragedy of the death of his father, coupled with poverty and unemployment, was destroying the soul of the sensitive man. One day while sitting in his house, he heard a knock at the door. He was a friend of his father. After offering his condolences, he said:
thousand Dirham”Did your father leave anything for you?”
“Then take this thousand Dirham; try to turn it into a capital, and meet your expense from its profit”.
Saying these words he went away. Ibne Sayyaba, happy as he was, went to his mother and showing the money told her the story. The same day, he used the money in purchasing some merchandise and opening a shop; and set his heart to it. He made a rapid progress. Soon after he realised that not only he had met his household expenses from the profit, but also the capital had increased to a great extent. Now he thought of performing Hajj Pilgrimage, and approached his mother for her advice. She said, “First you should repay the thousand Dirham which has brought such prosperity to us, and then you may go to Makkah for Hajj.”
He went to see the friend of his father, and placing a purse of one thousand Dirham before him, said, “Please accept your money back.” The man thought that Ibne Sayyaba was returning the same money because it was not sufficient for any trade. So he said:
“If the amount is insufficient I can increase it.”
“Good God, it was not insufficient. It has brought great prosperity to us and since I am now quite well off financially, I have come to repay your money, and to express my thanks to you, particularly when I have decided to go on pilgrimage to Makkah.
He came to his home and packed his luggage for Makkah.
After performance of the Hajj pilgrimage, he came to Medina and went to see Imam Jaffar as Sadiq (AS) along with other pilgrims. There was a huge crowd in the house of the Imam Jaffar as Sadiq (AS). Being young he chose to sit at the far end of the gathering, and from there watched the people coming and going; and heard their questions and the answers given by the Imam Jaffar as Sadiq (AS). When the house became nearly empty, Imam Jaffar as Sadiq (AS) pointed to him and said:
Imam Jaffar as Sadiq (AS) said: A believer is the brother and guide of another believer. He does not betray or oppress him, nor does he ever cheat his brother. A believer never breaks his promise.
“What can I do for you?”
“I am Abdur Rehman, son of Sayyaba, of Kufa (from the tribe of Bijilly).”
“How is your father?” asked Imam Jaffar as Sadiq (AS)
“Ah! Ah! May Almighty Allah (SWT) have His mercy upon him. Did he leave anything for you?”
“No, he didn’t”
“Then how could you perform Hajj Pilgrimage?”
“After the death of my father we were in distress. On one side his death and on the other side poverty and unemployment, were crushing us extremely. Then one day a friend of my father gave me one thousand Dirham and advised me to invest the amount in business. I followed his advice and from its profit I came to perform Hajj Pilgrimage”.
Before he could finish his story, Imam Jaffar as Sadiq (AS) said, “Tell me what did you do about the money of your father’s friend?”
I refunded the amount on the advice of my mother before coming out for Hajj Pilgrimage”.
“Very good. Do you like me to give you an advice?”
“May I be your ransom; of course”
Imam Jaffar as Sadiq (AS) said, “Be truthful and righteous. A truthful and righteous man is a partner in the wealth of others”.
