SB 9.11.8
kadacil loka-jijñasur
gudho ratryam alaksitah
caran vaco ’srnod ramo
bharyam uddisya kasyacit
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami continued: Once while Lord Ramacandra was walking at night incognito, hiding Himself by a disguise to find out the people’s opinion of Himself, He heard a man speaking unfavorably about His wife, Sitadevi.
