3-    The Sunset Prayer (Maghrib): Its time begins with sunset, i.e., the disappearance of the entire disk of sun. It finishes when the redness (evening twilight) in the western horizon disappears.

4-    The Nightfall Prayer (^Isha’ ): Its time begins with the disappearance of the redness in the western horizon and remains until the appearance of the true dawn.

5-    The Dawn Prayer (Fajr): Its time begins with the appearance of the true dawn, which is a white horizontal light that appears in the eastern horizon. Its time remains until sunrise.

Every pubescent, sane and pure Muslim is obligated to perform these prayers in their times. A woman is pure (tahir) when she is clear of menstruation and post-partum bleeding. It is unlawful, without an Islamic excuse, to perform these prayers ahead of their times or to delay them until their times have passed. Extreme sickness or traveling (with certain conditions) constitute examples of excuse for advancing or delaying the prayers.
