Can technology like computers and search engines, such as Google and Opera, be used despite the possible influence of Shaytan, given that even in rocket science, Jack Parsons, a self-claimed Satanist, attributed his success to Shaytan's help?
Yes, we are allowed to use any useful technology even if some persons who are involved in it are doing wrong. We should avoid doing wrong and use the technology in the lawful way. Knowledge is for all human beings no matter who invented any specific technology.
'Wassalam.
