Chandogya Upanishad 7.15.3

7.15.3

atha yady apy enān utkrāntaprāṇāñ chūlena samāsaṃ vyatiṣaṃdahet \
naivainaṃ brūyuḥ pitṛhāsīti na mātṛhāsīti na bhrātṛhāsīti na svasṛhāsīti nācāryahāsīti na brāhmaṇahāsīti \\715.3\

‘On the other hand, when the Prāṇa has departed from them, even if one piles them together, dismembers them with a fork and burns them up, surely people would not say to him, “You are a slayer of your father”, nor “You are a slayer of your mother”, nor “You are a slayer of your brother”, nor “You are a slayer of your sister", nor "You are a slayer of your preceptor", nor "You are a slayer of a Brāhmaṇa".
