Shaykhul-Islam Ibn al-Qayyim (may Allah have mercy upon him) mentioned that the Commander of the Believers Umar Ibn al-Khattaab (may Allah be pleased with him) said:
If the person will leave from his home and upon him are the sins similar to the mountains of Tihaamah. When he hears the knowledge, he has fear (of Allah’s punishment), returns back and repents. Then he leaves to go back to his home and there are no sins upon him. Based upon this, do not separate (yourselves) from the sittings of the Ulamaa.
