अश्रद्धया हुतं दत्तं तपस्तप्तं कृतं च यत्। असदित्युच्यते पार्थ न च तत्प्रेत्य नो इह॥
aśraddhayā hutaṃ dattaṃ tapastaptaṃ kṛtaṃ ca yat asadityucyate pārtha na ca tatpretya no iha
Meaning
Whatever is done without faith, whether it be sacrifice, austerity, gift, or anything else, is called Asat (meaning "Unreal"), for it is the negation of Sat, O Arjuna! Such an act has no significance, here or hereafter.
