A brief look at the Life of Imam Hussain (a.s)
(This is) an account of the Imam after al-Hasan b. Ali, peace be on him, (giving) the date of his birth, the evidence of his Imamate, the age he reached, the period of his succession (khalifa), the time and cause of his death, and the place of his grave. (It also provides) a selection from the (historical) reports about him.
The Imam after al-Hasan b. Ali was his brother, al-Husayn b. Ali (who was) the son of Fatima, daughter of the Apostle of God, may God bless him and his family, through the designation (nass) of his father and grandfather, peace be on them, and the testamentary bequest (wasiyya) of his brother, al-Hasan, peace be on him. His kunya was Abu Abd Allah (glory be to Him).
He was born in Medina, on the fifth of Shaban in the year 4 A.H. (626). His mother, Fatima, peace be on her, brought him to the Apostle of God. The latter was delighted with him and named him Husayn.
He sacrificed a ram on his behalf in the rite of aqiqa.
On the testament of the Apostle of God, he and his brother are the two lords of the youth of Heaven, and by unanimous agreement, they were the grandsons of the Prophet of Mercy.
Al-Hasan b. Ali, peace be on them, was like the Prophet, may God bless him and his family, from his head to his chest, while al-Husayn was like him from his chest to his feet.
They were the two dear ones of the Apostle of God among all his family and children. [Zadhan reported on the authority of Salman, may God be pleased with him:]
I heard the Apostle of God, may God bless him and his family, say concerning al-Hasan and al-Husayn, peace be on them: O God, I love both of them. Therefore love them and love whoever loves them Then he said: Whoever loves al-Hasan and al-Husayn, is one whom I love. Whomever I love, God loves, and whomever God loves, He will cause to enter Heaven.
Whoever hates them, I hate and God hates.
Whomever God hates, He will cause to enter the Fire. Then he said: These two sons of mine are my two plants of sweet basil (to sweeten) the world.
