The Book of Drinks
وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا عَبْدُ الْوَهَّابِ الثَّقَفِيُّ، حَدَّثَنَا إِسْحَاقُ بْنُ، سُوَيْدٍ بِهَذَا الإِسْنَادِ إِلاَّ أَنَّهُ جَعَلَ مَكَانَ الْمُزَفَّتِ الْمُقَيَّرِ .Ishaq b. Suwaid reported through the same chain of transmitters but for the difference that he substituted the word" gourd" for" waterskin" (meant for preserving wine)
From Sahih Muslim, whose reports the scholars accept as authentic.
