What is the ruling on participating in a draw for an electronic screen when purchasing electronic parts worth a certain value, and what is the ruling on taking the participation card from the seller, and what is the ruling on the gifts found on tissue boxes, and what is the extent of the validity of the statement permitting the taking of bank interest and spending it on poor Muslims?

The question encompasses four matters: raffles and promotional gifts from commercial stores, reviewing fatwas concerning dealings with usurious banks, and investing money in usurious banks and donating their profits, for each of which reference has been made to previous fatwas. As for someone who repents from investing their money in usurious banks, they are obligated to donate the interest to the poor and for charitable causes and the interests of Muslims.
