“I was a Christian, and became a Muslim. I went on the holy pilgrimage and then went to see Imam Sadiq (a.s) and said: “I was a Christian, and became a Muslim.” Imam Sadiq said: “What did you see in Islam?” I said: “The Almighty God's statement: “Thou knoweth not (before) what was Revelation, and what was Faith; but We have made (the Quran) a Light, wherewith We guide such of our servants as We will” [The Holy Quran: Shura 42:52] The Imam (a.s) said: “In fact God has guided you.” Then he said three times: “O' God! Please guide him.” And added: “O' my son! Ask me for whatever you wish.” I said: “All my family members are Christian. My mother is blind, and I have to be with them since my father has no one else to rely on. My parents like me to eat and drink with them from the same set of dishes.” Imam Sadiq asked: “Do your parents eat pork.” I said: “No. They do not even touch it.” Imam Sadiq said: “Fine. Take care of your mother. Treat her well and do not leave her alone when she dies. Take care of her burial yourself. Do not inform anyone that you have come to see me. God willing you will come to see me in Mina.” Zakariya said: “I went to see him in Mina. A lot of people had surrounded him. He was like a school teacher who was constantly asked questions by the people. Then when I went to Kufa I treated my mother with kindness. I fed her myself. I cleaned her clothes and her head myself. I served her myself. Then my mother told me: “O' my son! You never treated me this way when you had our own religion. What is this kind of behavior I observe since you have quit our religion and have accepted Islam?” Then I told her: “I was instructed to do so by a man who is a grandson of our Prophet.” My mother asked: “Is that man a Prophet?” I said: “No. But he is the grandson of the Prophet.” My mother said: “O' my son! This man is a Prophet since what he has instructed you to do is one of the decrees of the Prophets.” I said: “Dear mom. There will come no Prophet after our Prophet. He is a descendent of the Prophet.” My mother said: “Your religion is the best religion. Please present it to me.” Then I presented it to her and she accepted Islam. I taught her how to pray. She performed her noon, afternoon, evening and night prayers. At night her disease overtook her. She asked me to teach her again what I had taught her about Islam. And I did so. My mother witnessed to Islam and passed away. In the morning the Muslims performed her ablution and covered her in cloth. I prayed over her body and buried her.”
