Hafiz Muhammad Ameen
1760. Commentary: The world is perishable and the reward of the Hereafter is everlasting; therefore, there is no comparison between them. That is, the reward for the two Sunnah (supererogatory) units of the Fajr prayer is better than being given the entire world. Therefore, they should not be omitted even during travel.

Hadith Commentary: Benefits and Issues: From this, it is understood that the observance and regularity of the two rak‘ahs of Sunnah before Fajr in the Hereafter is such a cause of reward that it is more valuable and beneficial than the world and all that is in it. This is because everything in the world and whatever it contains is temporary and perishable, whereas the reward of the Hereafter is everlasting and imperishable.
