Hadith 6:951
Abu Bakr narrated to us, he said: Hushaym narrated to us, from ‘Imran ibn Abi ‘Ata’, he said: I witnessed the death of Ibn ‘Abbas, and Ibn al-Hanafiyyah took charge of him, so he built a structure over him for three days.
حدثنا أبو بكر قال ثنا هشيم عن عمران بن أبي عطاء قال شهدت وفاة بن عباس فوليه بن الحنفية فبنى عليه بناء ثلاثة أيام
