Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 24
Sanskrit:
कथं राममसम्भ्रान्तं जित्वाजेयं सुरासुरै: ।शाल्वेनाल्पीयसा नीत: पिता मे बलवान् विधि: ॥ २४ ॥
ITRANS:
kathaṁ rāmam asambhrāntaṁjitvājeyaṁ surāsuraiḥśālvenālpīyasā nītaḥpitā me balavān vidhiḥ
Translation:
[Lord Kṛṣṇa said:] Balarāma is ever vigilant, and no demigod or demon can defeat Him. So how could this insignificant Śālva defeat Him and abduct My father? Indeed, fate is all-powerful!
