What is the ruling on mentioning Almighty God in a place where there is idle talk, obscenity, or immodest pictures, and is it better to remain silent or to engage in remembrance in this situation?

The Prophet (peace be upon him) used to remember Allah in all his states. It is also recommended to remember Allah in places where people are heedless, for it indicates faith and a strong attachment to Allah the Almighty. Therefore, there is no harm in performing dhikr in any state. However, one must condemn sin with their hand, tongue, or heart if they are unable to do so otherwise.
