佛說觀彌勒菩薩上生兜率天經 1.22

1.22

The Buddha said to Upāli: “Listen closely now: in future ages, this Maitreya Bodhisattva will serve as a great place of refuge for sentient beings. If there are those who take refuge in Maitreya Bodhisattva, you should know that these people will attain non-retrogression on the supreme path. When Maitreya Bodhisattva becomes a Tathāgata, Arhat, Samyaksaṃbuddha, such practitioners, upon beholding the Buddha's light, will immediately receive the prediction [of awakening].”
