Subhúti Thera visits the Buddha with a companion, and the Buddha asks him who his companion is. Subhúti answers that he is the son of a believing disciple and has gone forth from a believer's home to homelessness. The Buddha then asks Subhúti if his colleague conforms to the traditional signs of the believer. Subhúti begs of the Buddha to define these signs, and the Buddha explains them at length. A.v.337f. The Commentary says that the monk was the son of Anáthapindika and therefore Subhúti's nephew (AA.ii.865).
