How should we spend from whatever we have?

Verses 26-30 of Chapter 17

And give to the kinsman his due, and to the Miskin (poor), and to the wayfarer. But spend not wastefully (your wealth) in the manner of a spendthrift. Verily, the spendthrifts are brothers of the Shayatin (devils), and the Shaytan is ever ungrateful to his Lord. And if you turn away from them and you are awaiting a mercy from your Lord for which you hope, then, speak unto them a soft, kind word. And let not your hand be tied (like a miser) to your neck, nor overextend it (like a spendthrift), so that you become blameworthy and in severe poverty. Truly, your Lord expands the provision for whom He wills and straitens (for whom He wills). Verily, He is Ever All-Knower, All-Seer of His servants.

Verses 67 of Chapter 25

Those who, when they spend, are not extravagant and not niggardly, but hold a just (balance) between those (extremes).
