佛說五無返復經 1.3

1.3

一時佛在舍衛國祇樹精舍，與千二百五十比丘俱。時有一梵志在羅閱祇國，聞舍衛人多慈孝順、奉經修道、供事三尊，便到舍衛國。見父子二人耕地，毒蛇齧殺其子。父故耕，不視其子亦不啼哭。

At one time, the Buddha was staying in the Jetavana vihāra in the country of Śrāvastī, together with twelve hundred and fifty monks. At that time, there was a brahmacārin in the country of Rājagṛha who heard that the people of Śrāvastī were largely compassionate and filial, upheld the scriptures and cultivated the Way, and made offerings to and served the Three Honoured Ones; he therefore went to the country of Śrāvastī. There he saw a father and son plowing the land. A venomous snake bit and killed the son. The father went on plowing as before, neither looking at his son nor weeping.
