680 – ʿAmr ibn Shuʿayb, from his father, from his grandfather (may Allah be pleased with him), reported: “The Messenger of Allah ﷺ forbade the sale of ʿurbān.” Mālik transmitted it and said: “It has reached me on the authority of ʿAmr ibn Shuʿayb in this wording.”⦗1⦘

Hadith grading:
This ḥadith is weak.
In al-Talkhīṣ the gist is as follows: all the available chains end with ʿAmr ibn Shuʿayb → his father → his grandfather.
• It was narrated by Mālik, Abū Dāwūd, and Ibn Mājah; in their chain is an unnamed transmitter—said to be ʿAbd Allāh ibn ʿĀmir al-Aslamī or Ibn Luhayʿah—both of whom are weak.
• Al-Dāraqutnī and al-Khaṭīb also related it; their chain includes al-Haytham ibn al-Yamān, whom al-Azdī declared weak, while Abū Ḥātim held him to be truthful (ṣadūq).
• Al-Bayhaqī transmitted it by way of ʿĀṣim ibn ʿAbd al-ʿAzīz from al-Ḥārith ibn ʿAbd al-Raḥmān ibn ʿAmr ibn Shuʿayb.
• ʿAbd al-Razzāq narrated it as a mursal report from Zayd ibn Aslam and remarked: “It is weak in addition to being mursal.”

Vocabulary notes:
• ʿurbān (earnest money): pronounced with a ḍammah on the ʿayn, followed by a silent rāʾ, a fatḥah on the bāʾ, then an alif and a final nūn. Alternative vocalisations include ʿarbūn, arbūn, ʿurubān, and arubān. The term refers to the practice whereby the buyer hands the seller a portion of the price and stipulates: “If I proceed with the purchase, this counts toward the price; if not, it remains the seller’s.”
