佛說觀佛三昧海經 3.48

3.48

佛告父王：「是諸比丘前世之時，以惡心故謗佛正法，但為父故稱南無佛，生生常得聞諸佛名，乃至今世遭值我出，見佛色身及見眾僧，聞佛所說懺悔眾罪，因懺悔故諸障消除，諸障除故成阿羅漢。」

The Buddha said to his father the king: "These monks in a past life, with an evil mind, slandered the correct Dharma of the Buddha. Merely for the sake of their father did they recite 'Homage to the Buddha.' Life after life they were constantly able to hear the names of the Buddhas, until in this present life they encountered my appearance, saw the Buddha's form-body and saw the Saṅgha, heard what the Buddha taught, and repented their manifold sins. Because of repenting, their various obstacles were eliminated; because their obstacles were eliminated, they became arhats."
