What is the ruling on earning from the Clixsense website for viewing advertisements, and from the Ads.Hsoub.com website through affiliate marketing, or displaying random advertisements, or leasing advertising space?

Browsing permissible advertisements that do not contain nude images or promote forbidden things like gambling and usury, is not problematic in exchange for a known fee from the website. Similarly, displaying permissible advertisements and taking a fee for them, or leasing advertising space, is permissible, provided that the advertisements are not forbidden or promoting something forbidden. If it is known that the renting party promotes what is impermissible, then it is not allowed to deal with them.
