I got so seriously ill that my tongue got numb and I could not talk. Then, I decided to go to visit the Shrine of Imam Ar-Ridha’ (a.s.) to pray to God the Highest and set the Imam (a.s.) up to intercede on my behalf to Him so that God would heal my ailment and I would be able to talk. Then I rode on a donkey, set out for Mashhad and went to visit Ar-Ridha’ (a.s.). I stood at the position of the Imam’s head and said two units of prayers and then went into the position of prostration. I said as many prayers as I could while crying and seeking the intercession of the tomb owner in the presence of God the Highest to heal my ailment and help me become able to talk.Then I fell asleep while I was prostrating. I saw in a dream that the grave opened up and an old tanned man walked out, approached me and told me, ’O Aba Nasr! Say: There is no god but God.’ I pointed at my tongue and meant to say how I could speak with a closed-up tongue.’ He (a.s.) shouted at me saying, ‘Are you denying His Power? Say: There is no god but God.’ Then my tongue opened and I said, ‘There is no god but God.’ Then (after I woke up) I walked back home and kept saying, ‘There is no god but God. I can talk.’ Then after this my tongue never became numb like that again.”
