The Chief Scholar, Ibn Qulawayh al-Qummi, Kaamil al-Ziyarat, Addendum
My father and Muhammad ibn Hassan both narrates to me from Hasah ibn Mattil, from Sahl ibn Ziyad, from Abi Hashim al-Ja'fari (refers to Dawud ibn Qasim ibn Ishaq ibn Abdillah ibn Ja'far ibn Abi Talib [as] who was one of the high ranked and noble companions of the AhlulBayt [as] and the companion of Imam Rida, Imam Jawad, Imam Hadi and Imam al-Askari [as])
When Abul Hassan (Imam al-Haadi [as]) was ill, he sent for Muhammad ibn Hamzah and I.Muhammad ibn Hamzah arrived there before I did and told me that Imam [as] kept saying, 'Send some one (on my behalf) to the Haa'ir! Send some one (on my behalf) to the Haa'ir!'
I said to Muhammad ibn Hamzah, 'Why did you not say that you would go to the Haa'ir (on his behalf)?!'
Then I went to the Imam [as] and said, 'May I sacrifice myself for you! I will go the Haa'ir.'
Imam replied, 'Plan it carefully, for Muhammad cannot keep this matter hidden from Zayd ibn Ali and I do not want him to find out about this.'
I mentioned this to Ali ibn Bilal and he asked, 'Why does the Imam [as] want to send someone to the Haa'ir while he is (as sacred as) the Haa'ir?!'
I went back to Askar (Samarra) and went to visit the Imam [as]. When I was about to leave, the Imam [as] asked me to stay. Once I felt comfortable, I mentioned that which Ali ibn Bilal had said.
Therefore the Imam said:
'Why did you not reply to him saying that the Messenger of Allah [saw] used to circumambulate the Kaaba and kiss the Hajar al-Aswad even though the sanctity of theProphet [saw] and even a believer is greater than the sanctity of the House of Allah?!
(Moreover), Allah ordered him (the Prophet [saw]) to go to Arafah and stay in it (while he is more sacred than Arafah). This is because these are places in which Allah loves to be called upon.
And I love to have someone pray for me in a place where Allah loves to be called upon, and the Haa'ir is one of these places.'
Al-Amili, Wasail al-Shia, v.14, p. 537 (Extract from 'The Sacred Effusion', Sh Muhammad Khalfan)
It is narrated that Imam al-Sadiq (a) once got ill, and ordered someone who was near him to tell his people to hire someone, so that he may pray for him near the grave of al-Husayn (a). So they found a person, and told him to do what is required.
He said: I will go, but al-Husayn (a) is an Imam who must be compulsorily obeyed (muftarad al-ta'a) and he (i.e. Imam al-Sadiq [a]) [likewise] is an Imam who must be compulsorily obeyed.[Aren’t they equal in status?]
So they went to Imam al-Sadiq (a) and informed him what the person had said. The Imam (a) said: What he said is correct. However, is he not aware that Allah has places, wherein supplications are accepted. And that spot [i.e. near the grave of al-Husayn (a)] is among those places.
'O God, carry us in the ships of Thy deliverance, give us to enjoy the pleasure of whispered prayer to Thee, make us drink at the pools of Thy love, let us taste the sweetness of Thy affection and nearness, allow us to struggle in Thee, preoccupy us with obeying Thee, and purify our intentions in devoting works to Thee, for we exist through Thee and belong to Thee, and we have no one to mediate with Thee but Thee!' Imam Sajjad ('A); Sahifa al-Sajjadiyya
