Shaykh Tusi has narrated through authentic chains from Imam Muhammad Baqir (a.s.) that a boy from Medina frequently visited the Prophet and was sometimes sent by him on errands. Sometimes the Prophet used send his letters through this boy.
When he remained absent for some days, the Prophet inquired the reason, and learning that the boy was seriously ill, went to see him with a group of companions. It was a blessing of the Holy Prophet (S) that whenever he used to speak to a person who could not speak up, by the Prophet’s blessing he used to begin speaking and he definitely gave replies to the Prophet. The Messenger of Allah (S) went to the boy and called out his name.
The boy immediately replied: “Here I am, O Abal Qasim.” He told him to say: I witness that there is no god Except Allah, and testify that I am the messenger of Allah. The boy looked to his father, but he didn’t say anything. Again the Prophet urged him and again he looked at his father but he again kept quiet. The Prophet told him the third time to repeat the words.
The father at last told him to do as he pleased. He immediately repeated the creed and died. The Prophet performed the funeral rites and thanked Allah that he had saved a child from Hell.
