The Long Āgama Sūtra 25.4

25.4

時，有倮形梵志姓迦葉，詣世尊所，問訊已，一面坐。倮形迦葉白佛言：「我聞沙門瞿曇呵責一切諸祭祀法，罵諸苦行人以為弊穢。瞿曇！若有言：『沙門瞿曇呵責一切諸祭祀法，罵苦行人以為弊穢。』作此言者，是為法語，法法成就，不誹謗沙門瞿曇耶？」

A naked wanderer from the Kāśyapa clan visited the Bhagavān. After they exchanged greetings, he sat to one side. That naked Kāśyapa said to the Buddha, “I hear that the ascetic Gautama criticizes all ritual practices and rebukes other ascetics, considering them corrupt. Gautama, suppose someone said, ‘The ascetic Gautama criticizes all the ritual practices and rebukes other ascetics, considering them corrupt.’ If someone says this is Dharma speech that accomplishes the teachings, would they not be slandering the ascetic Gautama?”
