There are certain supplications said in the mornings and the evenings.
Should the morning supplications be said immediately after waking up in the morning, or after the Fajr (Dawn) Prayer and throughout the day? Should the evening supplications be said immediately after sunset, or after the `Asr (Afternoon) Prayer and throughout the rest of the night? Please advise! May Allah reward you!
These supplications are meant to be recited when the time of Fajr (Dawn) Prayer begins, and when the time of Maghrib (Sunset) Prayer begins; whether before the Salah (Prayer), after it, or any time surrounding it.
