Sekhasutta 25.7

25.7

Sā kho panesā, mahānāma, brahmunā sanaṅkumārena gāthā sugītā no duggītā, subhāsitā no dubbhāsitā, atthasaṃhitā no anatthasaṃhitā, anumatā bhagavatā”ti.

And that verse was well sung by the Divinity Sanaṅkumāra, not poorly sung; well spoken, not poorly spoken, beneficial, not harmful, and it was approved by the Buddha.”
