We have been ordered to have a house in this world, how am I supposed to buy house if I have no income? how can i afford buying clothes? How can I make ends meet? How can I buy a car and drive it? I must have and income, and I must also have some extras so that I can do some other works as well; meanwhile, I must also share my income with people through Khums, Zakat, Infaq, holding ceremonies and parties and helping them. These are all mentioned in the holy Quran and narrations, but there must not be any attachment to all these things; because they are all fleeting and mortal; in other words, the mankind must not consider anything in the world as an idol, because they cause their stagnation and curb their movement toward the proximity to Allah Almighty.
The very Infaq, giving charity, Alms giving, Zakat, Khums, helping, and so on are the steps of moving toward the proximity of Allah Almighty. If an affluent and wealthy person avoids doing so, he will never gain the proximity of Allah Almighty.
