243- وبهذا الاسناد، عن علي بن محمد، عن أبي عقيل عيسى بن نصر قال: كتب علي بن زياد الصيمري يلتمس كفنا، فكتب إليه: إنك تحتاج (إليه) في سنة ثمانين. فمات في سنة ثمانين، وبعث إليه بالكفن قبل موته.
H 243 - It is narrated from the same chains from Ali bin Muhammad bin Abi Aqil Isa Ibn Nasr that he said: “Ali Ibn Ziyad Saymoori wrote and requested for a burial shroud.
