Abu Ismail Sandi says: I was in Sand when I heard that there is a proof for God among the Arabs. I left my homeland and to reach him , I smoothed the difficulty of the journey on myself. Until they introduced Imam Reza-7 to me.
I went to him even though I could not speak a single word of Arabic.
Therefore, I greeted him in my own language.
He also answered my greetings in my language. I was speaking in Sandi (Indian language) and he also answered me in the same language.
I said: I heard in Sand that there is a proof for God among the Arabs, so I have come to find him.
He said: Yes, I am that one. Ask any question you have and ask for anything you want.
I also asked him whatever I wanted.
When I got up to leave, I said:
I don’t know Arabic, pray that God will inspire me with the power to speak in Arabic so that I can talk to the Arabs.
So he put his honorable hand on my lips. From that time, I was able to speak Arabic well [1].
