"And indeed We gave David from Us bounty"—meaning: prophethood—"O mountains, repeat [Our] praises with him"—We said: O mountains, repeat [praises] with him; meaning: glorify [God].
﴿وَلَقَدْ آتَيْنَا دَاوُدَ مِنَّا فَضْلا﴾ يَعْنِي: النُّبُوَّة ﴿يَا جِبَالُ أَوِّبِي﴾ قُلْنَا: يَا جبال أوبي مَعَه؛ أَي: سبحي.
