If what you are about to do is something good, then do it and Bismillahirahmanirrahim . . .
Just do it. If Allah is happy with what are you doing, then what other people think about you it doesn't matter. People always talk. And keep on talking. If what they say to you is something good, take it. But, if what they say to you is something bad, throw it into garbage.
Keep Calm & Selawat.
Sallu Alan Nabiy !
