Loving him is recompense of prophethood...
Loving him is recompense of prophethood: Say: I do not ask of you any reward for it but love for my near relatives…[^1] His being is purified of every physical and spiritual filth and impurity: Allah only desires to keep away the uncleanness from you, O people of the House! And to purify you a (thorough) purifying.[^2] He is the son of the Prophet.
Come let us call our sons and your sons and our women and your women and our near people and your near people, then let us be earnest in prayer, and pray for the curse of Allah on the liars.[^3] He is the flower of the Holy Prophet (s.a.w). He is from the Prophet and the Prophet is from him. His Imamate is neither based on an armed uprising nor allegiance of the people. He is the chief of the youths of Paradise. He was infallible since the beginning of his life until the last moments.
The infallibility of the Holy Imam is the special belief of the Shias, which is not shared by any non-Shia sect. (Although many Ahl al-Sunnah researcher scholars consider them protected from sins).
As for the non-Shia sects, among them also all Hanafi, Shafei and most Hanbali consider Imam Husayn (a.s) on the right and Yazid on the wrong – quoting references here would unnecessarily prolong the discussion, hence I am just giving here a few names of scholars and the books in which they have mentioned those points: (1) Allamah Qastalani (Shahabuddin Abul Abbas Ahmad bin Muhammad died 923 A.H..) – Irshad as-Saari Sharh Sahih Bukhari, Vol. 10, Pg.
