Bhagavad Gita 9.31
क्षिप्रं भवति धर्मात्मा शश्वच्छान्तिं निगच्छति।कौन्तेय प्रतिजानीहि न मे भक्तः प्रणश्यति॥
kṣipraṃ bhavati dharmātmā śaśvacchāntiṃ nigacchati |kaunteya pratijānīhi na me bhaktaḥ praṇaśyati ||
Soon he becomes righteous and attains eternal peace; O Arjuna, proclaim thou for certain that My devotee never perishes.
He will soon attain spirituality and eternal peace. O Arjuna! Believe me, my devotee is never lost.
