Mahaditthisutta 1.12

1.12

Tattha natthi imināhaṃ sīlena vā vatena vā tapena vā brahmacariyena vā aparipakkaṃ vā kammaṃ paripācessāmi;

And here there is no such thing as this: “By this precept or observance or fervent austerity or spiritual practice I shall force unripened deeds to bear their fruit, or eliminate old deeds by experiencing their results little by little”—for that cannot be.
