A key for understanding the Qur'an's view on investment is to research the subject of prodigality in the Holy Qur'an. Prodigality is an investment that God Himself has defined it and has guaranteed its multiple profits. The Holy Quran defines encouragement, advice and competition to earn capital by the model of "prodigality" or "jihad with wealth". Agriculture, animal husbandry and industry are types of fields of prodigality and jihad with wealth. Prodigality is in the Holy Quran different from "charity", "zakat", "giving wealth", and "goodly loan" and other words that all mean a kind of giving of wealth and has its own semantic limits. The meaning of prodigality in the Holy Qur'an is very broad and does not only mean giving wealth to the needy. The cost that a person makes for his family is called in the Qur'an alimony. Similarly, the fee paid by the farmer for his land is called prodigality. God's land needs these expenses, and God provides hundreds of times this prodigality. "Wealth" and "fire" (capital and fire) are contiguous in most of the verses of the Holy Qur'an, and this may have caused some people to think that the Holy Qur'an has condemned the basis of wealth and capital, but it is not so. The contiguity of these two words in the Quran is because of the approach of most people in accumulating capital and not being prodigal.
