Will Allah forgive a son for the sins he commits, such as looking at pornographic websites and masturbating, because of his devotion to his blind mother whom his wife left to care for, and is it permissible for him to take his wife with him to avoid sins and leave his mother?

Firstly, a husband's absence from his wife for study or work exposes them to temptations. Viewing pornographic websites and masturbation are forbidden, and honoring one's parents does not absolve one from the sin of these transgressions.

Secondly, it is advised to return to your country to be with your mother and wife, or to bring them to live with you if possible.
