Is expiation required for someone who worked in a supermarket that sells beer and sold it once out of necessity, and is he considered cursed as mentioned in the Hadith?

There is no harm in working and earning as long as the work is permissible and not connected to anything forbidden. Some types of beer are alcohol-free and do not intoxicate when consumed; this is permissible. Other types are mixed with alcohol and intoxicate when consumed; this is forbidden and not permissible to partake in. As for selling beer containing alcohol in the past, the solution lies in seeking forgiveness, feeling remorse, and resolving not to return to it. The regulations concerning women's work must also be observed.
