Many have become accustomed to spending so much money that they need not to on things that are of no importance to them with the hope of oppressing or impressing people that may not even care. Why not invest it in a trade which Allah (Subhanahu wa ta'ala) is going to multiply it for you? "The likeness of the one who spends for the sake of Allah is like one who plants a seed that come out with seven ears, each ear having one hundred seeds, and for whosoever Allah wills, He multiplies that." (Baqara 261)
