بسم الله الرحمن الرحيم
Sometimes you expect too much from people and you get disappointed that your efforts brought no fruit. It’s a very hurtful situation. But when you expect from Allah SWT that your efforts (and inshaa’Allah reward) won’t go to waste no matter how people respond, that’s when you never get disappointed. It is then when you start seeing the fruits of your efforts even if they are the size of a berry. And sometimes those berry-sized fruits are much sweeter than huge tasteless watermelons! And Allah SWT knows best.
