Historians narrated that there were many miracles of Imam al-Hussayn (peace be upon him) even after the Taf tragedy. And among those extraordinary miracles the Holy Head's speech in several places, in which the statement of the righteousness of the Ahl al-Bayt (peace be upon them) and their connection to God Almighty is evident, and highlighting the horror of what was committed against them by the enemies.
In (Bihar) on the authority of (al-Manaqib) on the authority of al-Natanzi in (al-Khasa'es): When they brought the head of al-Hussayn (peace be upon him) to a place called (Qunasreen), a monk looked out from his silo to the head, and saw a bright light coming out of it (i.e. his mouth) and ascending to Sky high.
So he brought them ten thousand dirhams, and he took the head and put it into his cell. Then he heard a voice and did not see anyone. He said: Blessed are you, and blessed is the one who knows his sanctity. Then the monk raised his head and said: O Lord, in the right of Jesus (peace be upon him), you order this head to speak to me! The head spoke and said: O monk, what do you want? He said: Who are you? He said: I am the son of Mohammad al-Mustafa, and I am the son of Ali al-Murtadha, and I am the son of Fatima az-Zahra. I am the killed in Karbala, I am the oppressed, I am the thirsty.
So the monk put his face on Imam al-Hussayn's face, and said: I will not lift my face from your face until you say: I will intercede for you on the Day of Resurrection. Then the head spoke and said: Enter to the religion of my grandfather Mohammad (Allah’s prayers be upon him and upon his holy Household). The monk said: I bear witness that there is no god but Allah, and I bear witness that Mohammad is the Messenger of God. He then accepted to intercede for him.
In the morning, they took the head and dirhams from him. When they reached the valley, they saw that the dirhams had turned into stones.
The author of (al-Alam) mentioned about some of the ancient virtues: It was narrated that when the head of al-Hussayn (peace be upon him) was carried to the Levant, the night fell on them, and they went down with a man from the Jews, and when they were drunk, they said to him: We have the head of al-Hussayn. He said: Show him to me. So they showed him the head in the box, with light shining from him towards the sky.
So the Jew was astonished by the scene, so he asked them to keep it for the night, and then he said to the head (having seen him in that case): Intercede for me with your grandfather. God uttered the head, and said: My intercession is for the Mohammadians, and you are not a Mohammadian. So the Jew gathered his relatives, then took the head and placed it in a basin, poured rose water on it, and poured camphor, musk and amber on it, then said to his children and relatives: This is the head of the son of the daughter of Mohammad (Allah’s prayers be upon him and upon his holy Household).
Then he said: Woe to me, since I did not find your grandfather Mohammad (Allah’s prayers be upon him and upon his holy Household), so I greet him on his hands. Woe to me, as I did not find you alive, so I greet you and fight between your hands. If I become Muslim now, will you intercede for me on the Day of Resurrection? Then God uttered the head, then said in a tongue that was eloquent: If you become Muslim, then I am your intercessor. He said it three times, and was silent. So the man and his relatives converted to Islam.
Al-Majlisi says: Perhaps this Jew was a monk of Qunasreen, because he converted to Islam because of the head of al-Hussayn (peace be upon him), and he was mentioned in poems, and Al-Jawhari and Al-Jarjani included him in the Lamentations of Al-Hussayn (peace be upon him).
