Ways to invest my saved money in Germany in a halal way?
What is actually a halal investment? Your definition of halal investment is loose and subject to interpretation. On one hand, nothing is fixed in the financial world. You might get a 10 Year Germany Bund with a fixed coupon rate of 1%, but the real rate of return of this investment is far from fixed. It depends on the market environment, the inflation, etc. (Also, you can trade this investment on the secondary market at any time.) Moreover, the country can default. For example, nothing is "fixed" if you hold the Argentina bonds. You might think a saving account in the bank is a fixed investment. But again, what about the inflation? And if you talk with the account holders in Cyprus, you will understand there is no such thing that you are "guaranteed to profit a fixed amount each month or year". So, from this point of view, everything is "halal", because nothing is fixed and the risk of losing the principle is alway there.  On the other hand, if you assume that investing a government bond and having a saving account is not halal by definition, you will end up with a situation that every investment is not halal. Suppose you invest in a company. What does the company do with your money? Sure, they will use some of your money to buy equipments, hire new people, and so on. But they will always save some money as cash reserves to meet the short-term and emergency funding needs. Those cash reserves are usually in the form of highly liquid investment, such as short-term bonds, money market funds, savings in a bank account, etc. Because those investments are not halal per definition, is your investment in the company still halal? So in the end, you might just do whatever you want depending on your interpretation.
