This Nawafil (optional) Prayer consists of two phases; offering two Rak‘at when the sun has risen for a while but not enough to have heated up the environment. Once the latter has occurred, this is the second phase, in which one may offer four or eight Rak‘at. The first phase is known as Salatul-Ishraq and the second Salatud-Duha. It has also been named Salatul-Awwabin.
In some Traditions, however, the six Rak‘at Prayer offered in between Maghrib and ‘Isha’ Prayers is called Salatul-Awwabin.
