What is the ruling on contributing to pure companies listed in the clearing center's lists, knowing that these lists were recently issued and pertain to the previous year?

It is permissible to trade and invest in the shares of pure companies. The Maqasid Center for Economic Consultations, under the supervision of Dr. Muhammad bin Saud Al-Osaimi, is a trusted source for identifying pure and mixed companies. There is no harm in investing in a pure company based on the Center's report for the past year. If it is later discovered that the company deals with usury, purification becomes necessary, but there is no sin on the shareholder.
