اصحى على خير

Using this phrase is very simple. It is usually the very last thing said. You say it as you walk out the door. You say it before hanging up a late-night call. In a text, it’s the perfect sign-off before you put your phone away. If you are talking to a woman, say اصحي على خير (Is-ha-ee). For a group, use اصحوا على خير (Is-hoo). It’s a small change that makes a big difference.

Use it every night with your family. It’s perfect for friends after a late dinner. If you’re texting a crush late at night, it’s very sweet. It works well with colleagues you are close with. Basically, use it whenever sleep is the next step. It’s a cozy, comforting way to wrap up an interaction. It makes the other person feel seen and cared for.

Don't use this at 10:00 AM. It’s strictly for bedtime. Avoid using it for a 15-minute power nap. It feels a bit too heavy for a quick snooze. Don't use it in a very stiff, formal business meeting. In those cases, a simple "Good evening" is safer. It’s a personal phrase, so keep it for people you actually like!

In Arabic culture, sleep is often viewed as a vulnerable state. There is a deep-rooted tradition of wishing for safety during the night. Wishing someone to "wake up on goodness" is a protective gesture. It reflects the importance of the morning start. The concept of خير (khair) is central to Middle Eastern hospitality. It’s about wishing abundance for others without expecting anything back. It’s a verbal hug before the lights go out.

The most common cousin is تصبح على خير (Tisbah 'ala khair). That one means "May you become (find yourself) in goodness." They are almost interchangeable. In some regions, people respond with تلاقي الخير (Tila'ee el-khair), meaning "May you find goodness." The most standard response is وأنت من أهله (Wa anta min ahlo). This means "And you are from the people of goodness."
