Abu Umamah bin Sahl bin Hunayf narrates from his father (Sayyiduna Sahl bin Hunayf, may Allah be pleased with him) that the Prophet (peace and blessings be upon him) forbade two kinds of dates: al-ju'rur and al-hubayq. Some people would deliberately pick out the worst of their fruits and give them as zakah, so they were forbidden these two kinds of dates, and this verse was revealed: "And do not aim for the bad (of it), spending from it." [Surah al-Baqarah: 267]
Abu al-Walid narrated it with a connected chain, while Muslim bin Ibrahim and Muhammad bin Kathir narrated it from Sulayman bin Kathir as mursal (without the Companion).
