Magrib
In short
Maghrib is the Islamic call to prayer performed at sunset. It marks the beginning of the night prayer period in the Islamic calendar.
In plain words
When the sun goes down, Muslims stop their daily activities to pray. This prayer is done at the specific moment the sun disappears below the horizon. It is one of the five mandatory daily prayers.
A simple example
A person stops working at the end of the day to perform the Maghrib prayer as soon as the sky turns dark.
Why it matters
It helps Muslims structure their day around their faith. It also serves as a communal signal for the transition from day to night.
Easy to mix up
It is often confused with Isha, which is the prayer performed later when the night is fully dark.
