At Kusinārā 5.6

5.6

Evaṃ pasanno ahaṃ, bhante. Natthi imasmiṃ bhikkhusaṅghe ekabhikkhussapi kaṅkhā vā vimati vā buddhe vā dhamme vā saṅghe vā magge vā paṭipadāya vā”ti.

I am quite confident that there’s not even a single mendicant in this Saṅgha who has doubt or uncertainty regarding the Buddha, the teaching, the Saṅgha, the path, or the practice.”
