Reports  say that the Islamic funds and products have now been making inroads in the last couple of years and that even some government officials have been wooing funds from the Middle East, which were undeniably buoyed by the surging of oil revenues. However, a figure as high as US$1 trillion of institutional and retail investments has been mentioned which included some 400 odd Islamic funds was just estimates with no hard data to back up the numbers. There seems to be a positive connection here. Promoters of Islamic finance and funds often point to the scale of resources of the governments in the Islamic world — as one very amazing record of fund alone is that of Abu Dhabi Investment Authority that was reported to have assets of more than US$800 billion. Most Islamic funds are basically invested on the basis of getting good returns, and not based on Shariah principles.
