A brief look at the Life of Imam Hussain (a.s)
It did not bring down that to any other like them. God said in Surat Hal ata (known also as Surat al Dahr)
"And they give foods out of love for him, to the poor, orphans and prisoners We only feed you for the sake of God; we do not want reward or thanks from you.
Indeed we fear from our Lord a hard depressing day. Therefore, God will guard them from the evil of that day, and make them meet with ease and joy, and reward them with gardens and silk because they were patient." [Ch 76: Vr 8-12]
This statement is general to them, peace be on them, with their father and their mother.
The tradition contains their assertion of that and their awareness of it; both of which indicate that the illustrious verse was about the two of them and (that) the greatest proof (hujja) to creatures was through them both. In the same way the report about the Messiah, peace be on him, speaking in the cradle was a proof of his prophethood and God's special regard for him through miraculous acts (karama) which indicated his place and position with God with regard to merit (fadl) The Apostle of God, may God bless him and his family, had made clear his Imamate and the Imamate of his brother before him through designation (nass) when he said:
These two sons of mine are Imams who will experience difficulties. The testamentary bequest (wasiyya) of al-Hasan, peace be on him, to him indicated his Imamate,just as the testamentary bequest of the Commander of the faithful, peace be on him, to al-Hasan, peace be on him, indicated his Imamate just as the testamentary bequest of the Apostle of God, may God bless him and his family, to the Commander of the faithful, peace be on him, indicated his Imamate after himself.
According to what we have (just) mentioned the Imamate of al- Husayn, peace be on him, was confirmed after the death of his brother al-Hasan, peace be on him, and the obedience of all creatures to him was binding, although he did not summon them to (follow) him because of precautionary dissimulation (taqiyya) which he was following and because of the truce which existed between him and Mueawiya b. Abl Sufyan and the need to fulfil it.
In that he followed the same course as his father, the Commander of the faithful, peace be on him, in terms of the establishment of his Imamate after the Prophet, may God bless him and his family, despite (his own) silence (about it), and also of the Imamate of his brother after the truce despite (his) abstention (from politics) and (his) silence.
In that they were acting according to the practices (sunan) of the Prophet of God, may God bless him and his family, when he was blockaded in al-Shi'b and when he escaped Mecca as an emigrant by hiding in a cave and he was hidden from his enemies.
When Muawiya died, the period of the truce came to an end. (It was this) which had prevented al-Husayn, peace he on him, from calling (people) to (follow) him. Then he made public his (claim to) authority as far as was possible.
