Quranic Verses describing that Advice:
(16) My dear son, establish Salah , and bid the Fair and forbid the Unfair, and observe patience on what befalls . Surely, this is among the matters of determination; (17) And do not turn your cheek away from people, and do not walk on the earth haughtily. Surely, Allah does not like anyone who is arrogant, proud; (18) And be moderate in your walk, and lower your voice. Surely, the ugliest of voices is the voice of the donkeys."
