Subjugation of creation to the righteous

فَفَهَّمْنَـٰهَا سُلَيْمَـٰنَ ۚ وَكُلًّا ءَاتَيْنَا حُكْمًا وَعِلْمًا ۚ وَسَخَّرْنَا مَعَ دَاوُۥدَ ٱلْجِبَالَ يُسَبِّحْنَ وَٱلطَّيْرَ ۚ وَكُنَّا فَـٰعِلِينَ

And We gave understanding of it [i.e., the case] to Solomon, and to each [of them] We gave judgement and knowledge. And We subjected the mountains to exalt [Us], along with David and [also] the birds. And We were doing [that].
