Saudi King Abdul Azeez (rahimahullaah) said: Every person who has an advice (Ref 1) for us from the Book (i.e. the Qur’aan) or the Sunnah, we are ready at all times -whether (that advice) is from an elder or young person, a person of noble status or a person (considered) to be of low status. Whoever wants us to oppose anything from that (i.e. what the Book and Sunnah obligates), we will never accept it, for indeed Allaah commanded us to follow the Islamic legislation and that we adhere to it with our molar teeth (i.e. firmly adhere to it); so whoever is angry with us due to us adhering to our religion, then let him be angry with us as long as he wills.
