How Teachers Must Be with Students

Shaikh Ṣāliḥ Al-Fawzān, may Allāh protect him, said:

A teacher must behave kindly and gently with students, pray for them, and [do things to] make them want [to learn], for indeed, this is from the greatest means of teaching.   He must not come across to them with harshness, severity, and lack of compassion because this turns [people] away from knowledge.
