四分律比丘含注戒本 2.129

2.129

The Buddha was in Śrāvastī. A visiting bhikṣu spread bedding in a peripheral room to spend the night, and left without saying anything. The bedding rotted and spoiled, was bitten by insects, and became discolored. Seeing the fault, they reported it to the Buddha, who laid down this precept on this account.
