Allah teaches us to say before each prayer: “I have turned my face toward him who created the heavens and the earth, as one by nature upright, and I am not of the idolaters”. So this verse shows the direction and the finality religiously. In each work I do, my direction is toward Allah, and I am in harmony with the heavens, the earth, and all creatures, in their turning toward him.

Allah teaches us to say before each prayer: “I have turned my face toward him who created the heavens and the earth, as one by nature upright, and I am not of the idolaters”. So this verse shows the direction and the finality religiously. In each work I do, my direction is toward Allah, and I am in harmony with the heavens, the earth, and all creatures, in their turning toward him.
Therefore, my finality and my direction are toward Allah.
And as an application of this meaning, I announce that all the work I do, be small or great, some or a lot, short or long, is for Allah, the one, I don't associate anyone with him, and this is the meaning of his words: 
“say: Lo! My worship and my sacrifice, and my living and my dying are for Allah, Lord of the worlds”.

Exercise:
Whenever you begin a work, say:
“I have turned my face toward him who created the heavens and the earth, as one by nature upright, and I am not of the idolaters”, and ponder its meaning, then recite Allah’s saying: “say: Lo! My worship and my sacrifice, and my living and my dying are for Allah, Lord of the worlds”. 
Say Bismi Allah – in the name of Allah -, and then start your work.
