My Grandmother set up a trust fund to pay for education for her Grandchildren, but that we can ask for money from at any time, and any that is not used will be shared equally between the children as they each reach 25. Three have received theirs, and two have not. I recently asked for some money from this fund, and was sent an amount, but this time I noticed the money comes through a high interest account. I do not know either whether the shares are in halal companies, but could find this out...
