Abu Abdullah al-Husayn ibn Ali ibn Abi Talib, the fragrant plant of the Messenger of Allah (peace be upon him and his holy progeny)
and his likeness, who was in the ear of the Messenger of Allah (peace be upon him and his holy progeny) when he was born, the master of the youths of the people of Paradise,
the fifth of the People of the Cloak, and the son of the Lady of the Women.
His father was the one defending the Pond, and his uncle was the one with the two wings. He was nourished by the hands of Prophethood.

1782 - Abu Bahtar Muhammad ibn al-Hasan narrated to us, saying: Bishr ibn Musa narrated to us, saying: Abd al-Samad ibn Hassan narrated to us, saying: Umara ibn Zadhan narrated to us, from Thabit al-Bunani, from Anas ibn Malik, who said: A king of the heavens (or "the angels") sought permission to come to the Prophet (peace be upon him and his holy progeny), and he was granted permission. He said to Umm Salama: "Keep watch at the door; let no one enter." Then al-Husayn ibn Ali came, and he jumped in and began to sit on the shoulders of the Prophet (peace be upon him and his holy progeny). The king said to him, "Do you love him?" The Prophet (peace be upon him and his holy progeny) replied, "Yes."
The king said, "Then in your ummah, there are those who will kill him, and if you wish, I can show you the place where he will be killed." Then he struck his hand and showed him red dust. Umm Salama took some and sealed it in the corner of her garment, saying, "We used to hear that he would be killed in Karbala."
