Case 1: Existing green fruit sold without a retention stipulation — valid under Quduri's general rule; cutting follows.
Case 2: Existing ripe fruit sold without its tree — the main text still states a duty to remove.
Case 3: Existing fruit sold with a contractual obligation to remain until ripening — a defective sale.
Case 4: All the unseparated fruit sold except 10 ratls to be retained — prohibited in Quduri's stated rule.
The decisive concern changes between existence, added contract conditions and identification of the sold property.
