Shaykh Uthaymeen (rahimahullah),

We are created for the purpose of worshipping Allāh alone and everything upon the earth has been created for us [i.e. to aid us in this purpose and for lawful enjoyment].

هُوَ الَّذِي خَلَقَ لَكُم مَّا فِي الْأَرْضِ جَمِيعًا 

He it is Who created for you all that is on earth. (Al-Baqarah: 29) 

And amazing it is that nowadays our people busy themselves with what has been created for them at the expense of what they were created for. This is [tantamount] to foolishness – that they are busying themselves with that which was created for them at the expense of something which they were created for (and if this purpose is fulfilled will lead them to the Pleasure of their Lord, Inshā Allāh t’āla).
