Valmiki Ramayana Aranya Kanda Sarga 9 Shloka 4

राघव Rama, मिथ्यावाक्यम् lie, ते to you, न भूतम् never practised, न भविष्यति nor in future, धर्मनाशनम् destroying the character, परेषाम् other's, स्त्रीणाम् women, अभिलषणम् such desire, कुतः how can it come to you.

O Rama you never spoke untruth in the past nor will you speak in future. How can there be any desire in you to destroy the virtue of others' wives ?
