What is the ruling on downloading computer programs and electronic games that do not contradict the tenets of Islam and do not distract from religious duties, and is this considered theft?

If the aforementioned programs are of the first type (permissible to download), then there is no harm in downloading them. Otherwise, it is considered an infringement on their owners' rights. One must also ensure that the games are free from শরعي (Shari'ah) violations.
