[132] Now at that time the group-of-six bhikkhus (chabbaggiyā) went about holding up sunshades (chatta). Now at that time a certain lay follower (upāsaka) went to a pleasure park together with several disciples of the Ājīvakas. Those Ājīvaka disciples saw the group-of-six bhikkhus coming from afar holding up sunshades; having seen them, they said to that lay follower: "Sirs, these venerables of yours are coming along holding up sunshades, just like chief ministers of accounts (gaṇakamahāmattā)."
"No, sirs, these are not bhikkhus; they are wanderers."
They made a wager: "Bhikkhus, or not bhikkhus?" Then that lay follower, when they had come near, recognized them and criticized, complained, and spread it about: "How can the venerables go about holding up sunshades?"
Bhikkhus heard that lay follower criticizing, complaining, and spreading it about. Then those bhikkhus reported this matter to the Blessed One.
"Is it true, bhikkhus, ...?"
"It is true, Blessed One."
... Having rebuked them and given a talk on the Dhamma, he addressed the bhikkhus: "Bhikkhus, a sunshade is not to be used. Whoever should use one commits an offense of wrong-doing (dukkaṭa)."
