When the demigods are bereft of their chariots, when they forget how to use weapons, when they are fearful or attached to something other than fighting, or when their bows are broken and they have thus lost the ability to fight, Your Majesty does not kill them.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
न त्वं विस्मृतशस्त्रास्त्रान् विरथान् भयसंवृतान् । हंस्यन्यासक्तविमुखान् भग्नचापानयुध्यतः
na tvaṃ vismṛtaśastrāstrān virathān bhayasaṃvṛtān | haṃsyanyāsaktavimukhān bhagnacāpānayudhyataḥ
