THE PURPOSE OF WEALTH
Wealth and money are all for spending and providing the necessities of life, and not for piling up and leaving them behind in this world. The signs of wealth must be apparent in one's family and house. What is the use of working hard and not spending?
If the Almighty Allah bestows His blessings onto someone, these blessings must be apparent in that person's life.
The Prophet (SAW) of Islam stated: "He is not one of us who possess money but keeps his family away from his wealth."
Musa ibn Ja'afar stated: "A man's family members are his dependents. Thus whoever is bestowed with the blessings of Allah, should expand on his dependent's comfort, or else such blessings may be taken away from him."
BALANCED SPENDING
Allah regards balanced spending as a sign of faith and states in the Holy Qur'an: "And they who when they spend are neither extravagant nor parsimonious, and (keep) between these just mean. (25:67)."
A wise man would avoid borrowing money and would not take a loan for unessential purposes. An economy which is based on loans (with interests) received from banks and other establishments is logically wrong and is not praise worthy.
Buying goods on hire-purchase system, although makes your house look good, but takes away your comfort and peace of mind.
Why should one buy unnecessary goods more expensively and fill the pockets of bankers by installments? What kind of a life is it when everything is acquired at a hire-purchase price? Is it not better for one to wait and save his money in order to buy goods at the cheapest price?
It is true that earning money is difficult and it affects one's life a great deal, however, more important is that those with good earnings are always under debts of others. There are also many families with low earnings who live comfortably. The difference between the two is the way they spend their earning. Therefore, it is advantageous to a family that the man either takes control of expenditures or supervises the one who is responsible for it. Finally, it is reminded that meanness is just as bad as overspending. If a man has more earnings he must make his family more comfortable and provide their essential requirements as much as possible.
FAMILY EXPENDITURE
To arrange for alimony of wife is wajib (obligatory) for husband. That is, a man is duty-bound to pay for the expenses of his wife such as food, clothes, house, doctor, and medicine. He would be wrong not to maintain his wife and could be prosecuted by law.
One cannot expect a family to live without any expense. They all need food, medicine, clothes, and a place to live in. However, they might ask for unnecessary items in which case one can disobey them and not conform with their various desires.
A wise man would spend according to his earnings. He must classify the necessary commodities and purchase them in the order of priority whenever he can. He must also save some money for a rainy day. Some money must be put away for the house rent or purchasing a new place. He must not forget the electricity, water, gas and telephone bills. Taxes have to be paid and school fees must be kept in mind. He must seriously avoid overspending and not pay for unimportant items. A calculated manner of spending would never confront one with bankruptcy or debt.
