H 365 - It is narrated from a group of scholars from Abu Ja’far Muhammad Ibn Ali Ibn Husain Ibn Babawayh that Abu Muhammad Hasan Ibn Ahmad Mukattib said: I was in Baghdad in the year in which Shaykh Abul Hasan Ali Ibn Muhammad Saymoori passed away. I went to him a few days before his demise. He brought a holy letter to the people that read as follows:

“In the name of Allah, the Merciful, the Compassionate. O Ali Ibn Muhammad Saymoori, may Allah enhance the reward of your brothers for you, as you shall die within six days. Tie up your affairs together and do not appoint any successor to carry out your duties after your final transfer. The full occultation has begun and there shall be no appearance, but after permission of Allah, high His name is, and that shall be after a long time, hardening of the hearts and the earth being replete with inequity. Individuals from my Shia will claim to have seen me. Behold, whoever claims seeing me before the rise of Sufyani and the call, is a liar and a slanderer. And there is no power except by Allah, the High, the Great.” We transcribed copies of the holy letter and left him. When it was the sixth day, we returned to him as he was breathing his last. He was asked, “Who is your successor after you?” He said: “To Allah belongs the Order and He is its Sustainer.” He died. These were the last words heard from him. May Allah be pleased with him and may He please him.
