Indeed a great evil has entered upon Islaam and the Muslims under the guise of `Ahlul Bayt` may Allaah have mercy upon them, rather, a great deal of harm has been inflicted upon `Ahlul Bayt` due to those concealed under the banner of the Shi`ah.
Who was it that harmed `Alee`s heart, may Allaah be pleased with him, to the point that he used to say to them: `You who resemble men but are not men!`?
Who was it that stabbed Al Hassan ibn `Alee in his back side?
Who is it that invited Al Hussayn ibn `Alee and then turned him over to his opponents?
Who is it that invited Zayd ibn `Alee and then turned him over to his opponents?
Who was it that claimed to be a prophet under the guise of supporting `Ahlul Bayt`? It was the enemy of Allaah Al Mukhtaar ibn Abi `Ubayd ath Thaqafi.
Who was it that called to the Batinee sect that outwardly proclaims support for `Ahlul Bayt` but conceals disbelief and hypocrisy?
They murdered pilgrims in the sacred land and removed the black stone from its place!
Who was it that lied upon `Ahlul Bayt` and fabricated Ahadeeth about their virtue which only lower their status?
Who was it that caused the relapse of the Islaamic Khilaafah and caused the Tatar to conquer Baghdad? It was the two traitors; Ibn al `Alqami and Naseer ad Deen at Toosi, under the guise of the Shi`a, they then betrayed Allaah, His Messenger and the believers. Naseer ad Deen used to conceal disbelief in Allaah.
Who was it that used to join the Jews and Christians in their battles against the Muslims? It was the `Rafidah` as affirmed by ibn Katheer in `Al Bidaayah wan Nihaayah`.
Who is it that stood with the Jews in our era? They are the ones who murdered Palestinians in their tents.
Who is it that hides under the guise of being protective of Islaam while his actions are a witness that he dreads Islaam? It is the Imaam of misguidance al Khumayni. Read the book `Then came the role of the Majoos` by our brother `Abdullaah Muhammad al Ghareeb.
And when anyone speaks about these criminals they say: `You hate `Ahlul Bayt`.
Who is it that stood in the way of the call to the Book of Allaah and the Sunnah of His Messenger Muhammad, may the Salaat and Salaam be upon him? It was the Rafidah.
 This was before Muhammad ibn Saroor revealed his Hizbiyah, at the time when he used to travel to Damaaj and visit Shaykh Muqbil, may Allaah have mercy on him. He latter admitted that he had a group and Shaykh Muqbil advised him to forsake Hizbiyah. When his magazine `Majalatus Sunnah` was published, Shaykh Muqbil was pleased, but when he saw the calamities that it contained; defaming the people of knowledge, Hizbiyah and Suroriyah, he called it `Majalatul Bid`ah`.
