﴿ ۞ وَلَقَدْ ءَاتَيْنَا دَاوُۥدَ مِنَّا فَضْلًۭا ۖ يَٰجِبَالُ أَوِّبِى مَعَهُۥ وَٱلطَّيْرَ ۖ وَأَلَنَّا لَهُ ٱلْحَدِيدَ ﴾

“AND [thus], indeed, did We grace David with Our favour: “O you mountains! Sing with him the praise of God! And [likewise] you birds!” And We softened all sharpness in him,”

And verily We bestowed on David a great favour from Us — prophethood and scripture — and We said ‘O mountains repeat with him in praise by making glorifications and the birds too!’ read wa’l-tayra in the accusative as a supplement to the syntactical locus of jibāl ‘mountains’ in other words and We also called on them to glorify God with him. And We made iron malleable for him so that it was as dough in his hands.
