H 364 - A group of scholars narrated to me from Abu Ja’far Muhammad Ibn Ali Ibn Husain Ibn Musa Ibn Babawayh from Abul Hasan Salih Ibn Shuaib Taliqani that he narrated in the Dhul Qada of the year three hundred and thirty nine that: Narrated to us Abu Abdullah Ahmad Ibn Ibrahim Ibn Mukhallad that: I was present in Baghdad in the companionship of scholars of narration, may Allah bless them. Shaykh Abul Hasan Ali Ibn Muhammad Saymoori, may Allah sanctify his soul, said without being questioned with this respect, “May Allah have mercy on Ali Ibn Husain Ibn Babawayh Qummi.” The scholars noted the date of that day. Later, the news came that Ibn Babawayh had passed away on that very day. Abul Hasan Saymoori died after that in the mid-Shaban of the year three hundred and twenty nine.
