[Abu 'Eisa said:] One of them said in his Hadith: "A sip of it is unlawful."
He said: This Hadith is Hasan. Al-Laith bin Abi Sulaim and Ar-Rabi' bin Sabih reported similar to the narration of Mahdi bin Maimun from Abu 'Uthman Al-Ansari. Abu 'Uthman Al-Ansari's (a narrator in this chain) name is 'Amr bin Salim, and they say: "Umar bin Salim" (as well).
