Is a bequest regarding grain nullified if the grain is ground into flour?

Primary text

The bequest is considered revoked if the testator bequeathed grain and subsequently ground it into flour, or bequeathed flour and kneaded it into dough, or bequeathed dough and baked it into bread, or bequeathed bread and crumbled it into crumbs, or made it into *fatit* (small pieces). This revocation occurs because the original name (*ism*) of the item has been removed and it has been prepared for its intended use. This is the view of Al-Shafi'i.
