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]

Shaikh Jamaal Bin Fareehaan (may Allaah preserve him) said:

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) and speak concerning them with evil speech, 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! [End of quote [1]

Likewise, what would have Ibnul Mubaarak (rahimahullaah) said about the obstinate Ikhwaani speaking devil, Yasir Qadhi, and the silent human devils amongst the hizbiyyoon-those who still promote Yasir Qadhi?!
