Guidance from The Prophet (peace be upon him)
Hadrat Aishah (r.a.), the mother of the believers, reported: ‘The Messenger of Allah (peace be upon him) “The two rakah before the dawn (Fajr) prayer are better than this world and all that it contains.”’

The merits of offering the two-rakah optional Sunnah prayer before the obligatory ‘fajr’ prayer is better than this world and whatever it contains. If the merits of this two-rakah optional prayer is better than this world and whatever it contains, one can only imagine the importance, significance, merits, and rewards of an obligatory prayer in the Sight of Allah Subhanah!
