"بينما كانوا يقولون فيما بينهم إنه لا يمكن القيام بذلك، تم القيام به."

Simplified Meaning:

When people are spending their time doubting and saying something can't be accomplished, someone else comes along and gets it done without worrying about the negativity. Imagine a group of friends wanting to learn a new skill, like baking a complicated cake. Many of them might say it’s too hard and they can’t do it. But one person decides to try anyway, follows some instructions, and ends up baking a beautiful cake. This shows that while others were stuck in their doubts, the person who took action succeeded. It teaches us that instead of focusing on what might go wrong or listening to doubts, we should just go ahead and try. Taking action can often lead to unexpected success, even if others think it's impossible.
