Surah 38. Sad, Ayah 18

Lit., "We compelled" or "constrained".

See n. 2733 to xxi. 79. All nature sings in unison and celebrates the praises of Allah. David was given the gift of music and psalmody, and therefore the hills and birds are expressed as singing Allah's praises in unison with him. The special hours when the hills and groves echo the songs of birds are in the evening and at dawn, when also the birds gather together, for those are respectively their roosting hours and the hours of their concerted flight for the day.
