Mukhtasar Bukhari

Narrated Abdullah bin Umar (may Allah be pleased with them) that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "Allah will not take away knowledge after giving it to you, except by taking away the scholars along with the knowledge. Then people will seek religious verdicts from ignorant ones, and they will give verdicts based merely on their own opinions, thus they will go astray themselves and will lead others astray as well."
