In the name of Allah, the Entirely Merciful, the Especially Merciful.
People criticize!
We are in a habit of criticizing people's decisions, cultures, ideals, behaviours, lifestyle, food and even their bodies and physical forms. We believe that just because people share so much of their lives, we have an opinion in their lives.
SubhanAllah! People criticized the commands of Allah to change the direction of the Qiblah and some of His other commands too.
So who are you to think that people will not criticize you?
Check yourself first and if you are within the limits set by Allah ﷻ then do not allow the toxicity to get into you.
Rise above the criticism and see it as feedback and that is how you stay consistent in doing good. That is intelligent.
O Allah as you have beautified my outward appearance, beautify my character. May Allah ﷻ make us all better.
