Bhagavad Gita 17.22
And that which is given at an inappropriate place or time or to one who is undeserving, or with disrespect or contempt - such a gift is the result of ignorance.
अदेशकाले यद्दानमपात्रेभ्यश्च दीयते।असत्कृतमवज्ञातं तत्तामसमुदाहृतम्॥adeśakāle yaddānamapātrebhyaśca dīyate|asatkṛtamavajñātaṃ tattāmasamudāhṛtam||
