The prayer that has three raka’at is salatul

Explanation

Maghrib prayer has three rakats and is performed right after the sun sets. It is the fourth of the five daily prayers.

The other prayers have different numbers: Fajr has two, Zuhr has four, Asr has four, and Isha has four. Maghrib is unique with its three rakats.

This prayer must be done quickly after sunset because its time window is shorter than other prayers.
