Salaam and welcome, @maani_mohammed! The purification data is available on each of the ETFs’ respective product pages. For example, for ISDE, visit this page and scroll down to the section called “Purification Data”.
Your shares will be distributing shares (i.e. income will be paid out semi-annually on the shares). The dividends may include a portion of ‘impure income’ (i.e. income
prohibited under Shari’ah principles) which will be notified to investors. Islamic investors will be responsible for the purification of any such impure income in
accordance with Shari’ah principles (e.g. by donation to charity).
