四分律比丘含注戒本 1.334

1.334

佛在舍衛國，聽持三衣，不得有長。六群比丘，畜多長衣，或旦起衣，或中時衣，或晡時衣。彼常經營、莊嚴衣服，積而藏舉。比丘舉過，佛便訶已，因開重制。

The Buddha was in the country of Śrāvastī. He permitted the keeping of three robes, not allowing any extra. The group-of-six bhikṣus kept many extra robes—either morning-rising robes, midday robes, or late-afternoon robes. They constantly maintained and adorned their robes, accumulating and storing them away. The bhikṣus raised their fault, and the Buddha then rebuked them; because of this, he made an exception and reformulated the rule.
