Narrations state that after Imam as-Sajjad (peace be upon him) completed the burial of his father Imam al-Hussayn (peace be upon him), he walked to the body of his uncle, al-Abbas (peace be upon him), and he saw him in a condition that had left the angels anguished and caused the huris to weep even as they were in the chambers of Paradise. He fell upon it kissing his sacred neck and saying, “May the world after you be obliterated, O moon of Banu Hashim, and peace from me to you, O martyr, and the mercy of Allah and His blessings.”
He dug a grave for him and took him down in it by himself just as he had done to the corpse of his martyred father (peace be upon him). He said to Banu Asad, “There is someone with me to help me.”
Yes, he gave the opportunity to Banu Asad to participate in burying the martyrs, and he assigned for them two places, ordering them to dig two pits in the first of which he buried those slain from Banu Hashim and in the second those slain from among their companions. As regarding al-Hurr al-Riyahi, his corpse was taken away by his tribe that buried it where it now stands.
