How do Muslims say God bless you?

Could you please clarify for me how Muslims express the sentiment of "God bless you" in their culture and tradition? I'm particularly interested in understanding if there's a specific phrase or greeting that they use, and if it carries a similar meaning and intent as the common English phrase. Additionally, is this greeting commonly used in various Islamic contexts, such as during everyday conversations, religious gatherings, or as a form of blessing for someone embarking on a journey or facing a challenge? I'm eager to learn more about this aspect of Muslim culture and its significance.
