B.G 18.03

त्याज्यं दोषवदित्येके कर्म प्राहुर्मनीषिणः। यज्ञदानतपःकर्म न त्याज्यमिति चापरे ॥३॥

Some wise individuals say that actions should be relinquished as they are flawed, while others argue that acts of sacrifice (yajña), charity (dāna), and austerity (tapaḥ) should not be relinquished.

Gīta Tātparya 18.03

Since the word "manīṣiṇaḥ" or "wise persons" is used here, both viewpoints are acceptable, and we must understand them correctly. The key point to note is the difference between renunciation and relinquishment. When the wise talk about relinquishing the actions, they are recommending relinquishing the attachment to results and not abandoning the actions themselves. The concept 'relinquisher of the fruits of actions' will be further elaborated.

'मनीषिणः' इत्युक्तत्वात् तेऽपि अनिन्द्याः। अतः 'त्याज्यं दोषवत्' इत्यस्य अर्थः 'सङ्गं त्यक्त्वा फलं च' इति ॥३॥

Because of being called 'wise ones', they, i.e. those who hold the initial viewpoint, are also blameless. Therefore, the phrase 'tyājyaṁ doṣavat', i.e. 'to be relinquished like a fault' means 'to relinquish attachment and also the results'.
