Bhagavad Gita · 17.21

यत्तु प्रत्युपकारार्थं फलमुद्दिश्य वा पुनः।दीयते च परिक्लिष्टं तद्दानं राजसं स्मृतम्॥

yat tu pratyupakārārthaṁ phalam uddiśhya vā punaḥ dīyate cha parikliṣhṭaṁ tad dānaṁ rājasaṁ smṛitam

But charity given expecting something in return, or with a desire for its fruits, or given grudgingly — that is considered to be in the mode of passion.

— Bhagavad Gita 17.21
