بسم الله الواحد القهار
Sheikh Al-Saduq:
Narrated to me Mohammad Ibn Al-Hasan from Mohammad Ibn Al-Hasan Al-Saffar from Al-Abbas Ibn Ma'ruf from Hammad Ibn Isa from Rib'ee Ibn Abdullah who said: I said to Abi Abdullah(عليه السلام) in Medina: "where are the graves of the martyrs?" He(عليه السلام) said: "isn't the master of the martyrs near you, Al-Husain(عليه السلام)? by the one in Whose hands is my soul, four thousand disheveled angels are around his grave, covered with dust cry over Imam Husain(عليه السلام) until Judgment Day."
Footnote: Its chain is of the most authentic chains, its narrators are trustworthy, of the great and esteemed scholars.

Allamah Al-Hilli:
Sheikh Al-Tusi and Ibn Yaqoub have narrated through an authentic chain from Hassaan Al-Jammal who said the following:
“I once provided transportation for abu ‘Abd Allah, (عليه السلام), from al-Madinah to Makkah. When we arrived at Masjid of al-Ghadir Khum, he looked to the left side of the Masjid and said this.
‘That is the place where the Messenger of Allah(صلی الله وعليه وآله ) set foot when he said, “On whoever I have Divine Authority, Ali also has Divine Authority.” He then looked to the other side and said, ‘That is the place for the tent of abu so(i.e. Abu Bakr) and so(i.e. Umar) and Salim Mawla’ abu Hudhayfah and abu ‘Ubayda al-Jarrah, who on seeing him raising his hands, said to each other, “Look at his eyes turning like the eyes of an insane person.” Jibril at this time came with this verse of the Holy Quran:
“The disbelievers almost make you slip up, by their piercing eyes when they hear the Zikr and say that he is an insane person. It is not anything other than good advice from the Lord of the worlds.”’ [54:50–51] ”
Then he said, "O Hassaan if you were not my camel-driver, I would not have narrated to you this hadith."
