The reality of temporary life and the command to spend and fight in the way of Allah

Verily the life of this world is no more than a sport and frivolity. If you believe and fear God, he will give you your reward, and will not ask for your possessions.

If He asks for all you possess and insist upon it, you will become niggardly, and it will bring out your malevolence.

Beware! You are called to spend in the way of God, yet some among you close their fists. But he who is niggardly is so for his own self: God is above need, and it is you who are needy. If you turn away then God will bring other people in your place who, moreover, will not be like you.
