Isḥāq ibn Manṣūr narrated to us: Yaḥyā ibn Ṣāliḥ al-Wuḥāẓī informed us: Muʿāwiyah narrated to us. (Another chain:) Muḥammad ibn Sahl al-Tamīmī and ʿAbd Allāh ibn ʿAbd al-Raḥmān al-Dārimī narrated to me—and the wording is theirs—both from Yaḥyā ibn Ḥassān: Muʿāwiyah, that is, Ibn Sallām, narrated to us: Yaḥyā, that is, Ibn Abī Kathīr, informed me, saying: I heard ʿUqbah ibn ʿAbd al-Ghāfir say: I heard Abū Saʿīd say: Bilāl came with some Barnī dates, and the Messenger of Allāh, peace and blessings be upon him, said to him: "Where is this from?" Bilāl said: "We had some inferior dates, so I sold two ṣāʿs of them for one ṣāʿ, for the Prophet's, peace and blessings be upon him, food." The Messenger of Allāh, peace and blessings be upon him, said at that: "Oh! The very essence of usury! Do not do that. Rather, if you wish to buy dates, sell them in a separate transaction, then buy with its proceeds." Ibn Sahl did not mention "at that" in his narration.
