this for ten reasons that I have mentioned elsewhere (1).
One is that ‘Umar recited it aloud to teach the Companions.

This opening supplication, together with the opening declaration of Allah’s greatness, encompasses them all.
Another is that this opening supplication is devoted entirely to praising Allah, whereas others include petitions; and praise is superior to petition. This is why Sūrat al-Ikhlās is equivalent to one-third of the Quran: it is devoted entirely to describing the Most Merciful—blessed and exalted is He—and praising Him. This is also why “Glory be to Allah; praise be to Allah; there is no god but Allah; Allah is the Greatest” are the best words after the Quran. It follows that an opening supplication encompassing them is superior to other opening supplications.
Another is that most other opening supplications were used in voluntary night prayer, whereas ‘Umar taught (4) the people this one in obligatory prayer.
Another is that this opening supplication directly expresses praise of the Lord Most High, while affirming His attributes of perfection and majesty. By contrast, the opening supplication beginning “I have turned my face” describes the servant’s devotion to Him. How great is the difference (5) between the two!
