俱舍論疏 12.179

12.179

論「若一縷中至有衣分無衣」，牒救破也。若是一縷中無全衣故不見衣者，即應一縷上有衣，一分無全衣。

The treatise says: "If because in a single thread … there is a part of the cloth, not the cloth." He takes up their rescue to refute it: If it were because the whole cloth is not present in a single thread that cloth is not seen, then on a single thread there would be a part of the cloth, but not the whole cloth.
