Is cutting bread into four pieces before eating a Sunnah?

There is no specific guidance in the Sunnah regarding how to eat bread or cut it before eating, nor is there any text indicating the desirability of cutting it. Cutting bread is among the permissible customs, and no desirability or dislike is associated with it. The hadith prohibiting cutting bread with a knife is invalid and has no basis. However, it is desirable to cut it if doing so preserves what remains of it from getting soiled and protects it, especially with large-sized bread. This is considered good management and rational consumption.
