Imam Hussain (as) is the example for the self-conscious, uncompromising revolutionary, the one who advocated the rights of the oppressed. He is one of the near relatives of the Holy Prophet (pbuh) whom Almighty God orders us to love:
Say: I do not ask of you any reward for it but love for my near relatives; and whoever earns good, We give him more of good therein; surely God is Forgiving, Grateful. (42:23)
Imam Hussain (as) was a member of the family of the Holy Prophet (pbuh), whom Almighty God has kept uncleanness away from:
God only desires to keep away the uncleanness from you, O people of the House! And to purify you a (thorough) purifying. (33:33)
Imam Hussain (as) was one of those counted with the Holy Prophet (pbuh) when the contest of prayers with the Christians of Najran was staged:
And whoever disputes with you concerning him (Jesus) after what has come to you of knowledge, then say: Come let us call our sons and your sons and our women and your women and ourselves and yourselves, then let us be earnest in prayer, and pray for the curse of God on the liars. (3:61)
