Salaam Alaikum. It would be nice if the question was a bit more clear.
If what is meant by property investment is to invest in property in order to obtain income through the rise in property value, this is allowed.
If what is meant is investing ones funds in different investment opportunities, generally speaking this would be permissible. However, there are a long list of rules pertaining to it which cannot be explained in one email. If you have questions regarding specific forms of investment, for example those involving interest, etc. please send them our way.
Keep us in your prayers.
