In The Name of Allaah, The Most Merciful, The Bestower of Mercy
Ali Ibn Shaqeeq [rahimahullaah] said: I heard Abdullaah Ibnul Mubaarak [rahimahullaah] saying in the midst of the people: ”Leave the narrations of the Amr Bin Thaabit because he used to revile the Salaf [i.e. the pious predecessors]”. [Muslim 1/16]
How about if Ibnul Mubaarak [rahimahullaah] was to appear amongst us [today]! What would he say about those who speak ill of the companions of the Messenger [sallal-laahu-alayhi-wasallam], such as the likes of Mawdoodi, Sayyid Qutb, Taariq Suwaydaan, Hasan bin Farhaan al-Maaliki, Abul Hasan al-Maribi al-Misri and those who defend these people or keep silent about them!
