﴿ وَرَبُّكَ أَعْلَمُ بِمَن فِى ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ ۗ وَلَقَدْ فَضَّلْنَا بَعْضَ ٱلنَّبِيِّۦنَ عَلَىٰ بَعْضٍۢ ۖ وَءَاتَيْنَا دَاوُۥدَ زَبُورًۭا ﴾

“seeing that thy Sustainer is fully aware of [what is in the minds of] all beings that are in the heavens and on earth. But, indeed, We did endow some of the prophets more highly than others -just as We bestowed upon David a book of divine wisdom [in token of Our grace]”

And your Lord knows best all who are in the heavens and the earth thus endowing them each one with what He will according to the measure of their states. And verily We have preferred some of the prophets above others endowing each of them with a particular merit Moses with being spoken to; Abraham with Friendship; and Muhammad (s) with the Night Journey; and We gave David the Psalms.
