Amir’ul- Mu’minin longs to you, and likes to meet and look at you. Would you please hurry to visit and reside with him as you like? You are free to bring from your family, followers, and servants whom you like. You travel when you want, come when you want, and move however you want. And if you like that Yahya bin Harthama the mawla of Amir’ul- Mu’minin and the soldiers with him to accompany you in your travel, and it is up to you. We have ordered him to obey you.
Ask Allah to choose what is best for you until you will come to Amir’ul- Mu’minin. None of his (Amir’ul- Mu’minin al-Mutawakkil’s) brothers, his children, family, and close companions is more preferred to you near him, or of closer position to him than you, and he is not kinder, more loyal, or more faithful towards any of them than towards you.
The peace, mercy, and blessings of Allah be on you.’[^1] The worry of the people of Medina Al-Mutawakkil ordered Yahya bin Harthama to travel to Yathrib to bring Imam al-Hadi (a.s.) to Surra Man Ra’a and to investigate the accusation claiming that Imam al-Hadi (a.s.) had intended to resist the rule and revolt against the government. Al-Mutawakkil gave the letter, which he had written to Imam al-Hadi (a.s.), to Yahya. Yahya traveled to Yathrib.
When the people of Yathrib knew about his task, they worried and feared too much for Imam al-Hadi (a.s.) from the violence of the tyrant against him. They loved Imam al-Hadi (a.s.) so much, for he kept to the mosque of the Prophet (S) feeding their ulama’ with his knowledge, giving charities to their poor, and he had no any tendency towards the worldly life.[^2] Yahya began calming down people’s worry and fear and swore to them that he had not been ordered to do the Imam any wrong.
They believed him and calmed down. Searching the Imam’s house Yahya and his men searched the house of Imam al-Hadi (a.s.) thoroughly but did not find anything save copies of the Holy Qur'an and books of du’a. it appeared that what was imputed to the Imam (that his house was full of weapons and money) was false.[^3] Sending the Imam to Surra Man Ra’a Imam al-Hadi (a.s.) was forced to leave Yathrib to Samarra’. His family accompanied him in the travel.
Yahya, who admired the guidance and piety of Imam al-Hadi (a.s.), himself served the Imam during the travel. The caravan covered the desert until it arrived in Baghdad.
