I don't want to stir up religious animosity or controversy, it's a pointless endeavor. BUT. Referring to someone controlling your destiny is a very convenient and comfortable concept to absolve oneself of responsibility. If a person does nothing, he will have nothing. If a person works, has goals and the desire to achieve - he achieves them. Environment - imposes some difficulties/comfort. But external circumstances also shape ordinary people. Faith is for the soul, but not for business, wealth, and prosperity. Let's not try to mix reality and religion !
Well, let me explain it a bit more for better understanding. It is said that you need to work for what you want. And you need to work hard. But what you get comes from Allah in the form of Rizq. It could be anything from food to clothes to drinking water. The concept here is to keep on working, but when it comes to getting value for what you have worked for, that's in the hands of Allah. To a religious person, it is something you should believe without any question. But to those who are not from the same religion, you can take it as a form of motivation. There's someone always to give you, so all you need to do is work in order to earn it. That's it.
Everything will work out somehow, that's the thing that keeps us going in life right? So you can take this as you want. But the results will always be positive in the end. Never give up and just keep on working. Ups and downs are just a part of life. But only the end results matter.
