Giving dawah or advice is never an easy task. Especially when people begin to misunderstand you and your advice. However, I often have to remind myself and others, that, if you are sincere in trying to spread goodness to others whilst people misunderstand you; then let it be a reminder to continue improving yourself regardless of their thoughts and opinions.
This is because our job is to relay. As for guidance, that is in the hands of Allah سبحانه و تعالى. Continue your dawah regardless of whether or not the people you are advising accept the message, or just brush it under the carpet. For you have done your bit in tieing the camel; now the rest is in the Hands of Allah.
My first teachers, (my parents) and all those who Allah سبحانه و تعالى has blessed me with as teachers to this inheritance of our Prophet ﷺ have taught me never to be negatively swerved by public opinion.
