Awwal Waqt which is also known as Waqt Al-Fadheelah is the period within which it is highly recommended to perform the prayer. It starts when the real time of the Salah starts. Azan is not always declared on the real time but delayed in some places especially in some non Muslim countries.

Awwal Waqt for morning prayer is from Real Fajr till darkness of the sky starts decreasing.

Awwal Waqt for Dhuhr prayer is from midday till the shadow of things becomes to four sevenths of the thing and it is better not to delay it more than the time of two sevenths of things.

'Awwal Waqt for Assr prayer is after performing Dhuhr or from the time of two sevenths of the shadow till the shadow reaches six sevenths.

Awwal Waqt for Maghrib is from vanishing the eastern reddish ness till the end of western reddish ness in the horizon.

'Awwal Waqt for Isha prayer is from vanishing of western reddish ness till one third of the night.

Wassalam.
