Q 3: If
I woke up after sunrise. Should I offer the Fajr (Dawn) Prayer or not?
Some say that there is no need to offer it after sunrise.
You should offer the Fajr Prayer at its due time. It is not permissible to delay performing Salah beyond its due time except for an acceptable legal excuse such as sleep or forgetfulness. The Prophet (peace be upon him) said:
Anyone who misses a prayer due to sleep or forgetfulness should offer it when they remember it. There is no expiation for it but this.
Then he recited Allah's Words:
...and perform As-Salât (Iqâmat-as-Salât) for My Remembrance.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
