ومن ابتلعَ الحصاةَ، أو الحديدَ، أو النَّواةَ: أفطرَ، وقضى.
Translation: Whoever swallows a pebble, metal, or a fruit pit invalidates the fast and must make it up.
Pebbles, metal, and fruit pits are non-nutritive objects. Swallowing them invalidates the fast and requires qaḍāʾ under this ruling.
They are distinguished from ordinary food or medicinal intake, for which Quduri states a separate rule immediately afterward. This clause prescribes make-up, not the additional expiation.
