Shaykh Ibn ‘Uthaymeen said:
Whoever does you [a favour or] a good turn, particularly in terms of your religion, and [offering you sincere] advice, and encouraging you upon good and discouraging you against that which is bad, then [all of] this necessitates that you should love [and respect] them.
This is contrary to what some of the people do today, whereby if you were to encourage them upon good and [likewise] discourage them against that which is bad, or if you invited them or guided them to something which was good, then they would [be offended and] harbour hatred in their heart towards you. This [behaviour] is in [direct] conflict with common sense as well as the religion.
