726 – Ibn ʿUmar (d. 73 AH) said: “The Messenger of Allah ﷺ prohibited selling fruits until their soundness becomes evident; he forbade both the seller and the buyer.” Agreed upon.
In another wording: “When he was asked about their soundness, he would reply, ‘Until their blight has disappeared.’” (1)

— Vocabulary of the ḥadīth —
• al-thimār (fruits): with a kasrah on the thāʾ; plural of thamara, and it includes the produce of date-palms and all other trees.
• ḥattā yabdū (“until it appears”): from the verb badā without a hamzah, meaning “to appear after being hidden.” By contrast, badaʾtu (with a hamzah) means “I initiated” or “began with.” Al-ʿAynī noted that many manuscripts read “ḥattā yabdaw” with an extra alif after the wāw; this is incorrect—the alif must be omitted.
• ʿāhatihā (“its blight”): one says ʿāha al-māl yaʿūhu ʿuwūhan when property is struck by a blight. The root noun is ʿawhah, plural ʿāhāt. A ʿāhah is any pest or defect that damages or ruins crops or fruit.
