Imaam maalik: four not to take knowledge from

Imaam Maalik – may Allah have mercy upon him – said:

"Knowledge is not to be taken from four types of people:

* a foolish person who openly acts foolish, even if he reports the most narrations;
* an adherent of bid’ah who calls to his desires;
* a person who lies, even if I don’t accuse him of lying in hadith;
* and a righteous pious worshipper who does not accurately retain what he narrates."

Adh-Dhahabi, Siyar A’laam Al-Nubalaa' in his biography of Imaam Maalik.
