What is the ruling on someone who says "by Allah" unintentionally when asked about something? And what is the ruling on working in an airline company where the work time coincides with the Friday prayer? Is the employee excused?

For someone who swore unintentionally, whose tongue slipped into an oath without the intention of affirming it, such as saying "No, by Allah" or "Yes, by Allah" in a state of anger or persistence, this is a vain oath (yamin (definition) laghw) and is not considered binding. As for working in the company, there is no harm in it, and a person should not be prevented from working there because he might miss Friday prayer due to it. However, the worker should strive to attend Friday prayer, and the employer should enable him to do so, as long as his absence does not result in harm.
