Bhagavad Gita 17.28
अश्रद्धया हुतं दत्तं तपस्तप्तं कृतं च यत्।असदित्युच्यते पार्थ न च तत्प्रेत्य नो इह॥
aśhraddhayā hutaṁ dattaṁ tapas taptaṁ kṛitaṁ cha yat asad ity uchyate pārtha na cha tat pretya no iha
Translation
Whatsoever is wrought without faith, oblation, gift, austerity, or other deed, "Asat" it is called, O Pârtha; it is nought, here or hereafter.
What it means
Whatever is done without faith, oblation, gift, austerity or any deed, is called Asat, unreal; it is nothing here or hereafter. The closing formula weighs every act by its sincerity. Without faith, even virtue is weightless.

Chapter 17's final test: faithless action does not count - not punished, just void, in both worlds.
Something to reflect on
Which of my deeds, done without faith, turned out to count for nothing?
