Bhagavad Gita 17.21 — Rajasic charity
यत्तु प्रत्युपकारार्थं फलमुद्दिश्य वा पुनः। दीयते च परिक्लिष्टं तद्दानं राजसं स्मृतम् ॥
yattu pratyupakārārthaṃ phalamuddiśya vā punaḥ | dīyate ca parikliṣṭaṃ taddānaṃ rājasaṃ smṛtam ||
Meaning
A gift given to get something back, or with an eye on reward, or given unwillingly, is called rajasic.
