The Prophet ﷺ became thirsty near the Kaabah and asked for something to drink. He was brought some nabidh from the watering place. He smelled it and frowned, then said, "Bring me a bucket from Zamzam." It was poured over the nabidh, and he drank it.A man asked, "Is it forbidden, Messenger of Allah?"He replied, "No."This report is weak, because Yahya bin Yaman alone narrated it among the companions of Sufyan, and Yahya bin Yaman's hadith is not used as proof due to his poor memory and frequent errors.
أخبرنا الحسن بن إسمعيل بن سليمان قال أنبأنا يحيى بن يمان عن سفيان عن منصور عن خالد بن سعد
عطش النبي ﷺ حول الكعبة فاستسقى فأتي بنبيذ من السقاية فشمه فقطب فقال علي بذنوب من زمزم فصب عليه ثم شرب فقال رجل أحرام هو يا رسول الله قال لا وهذا خبر ضعيف لأن يحيى بن يمان انفرد به دون أصحاب سفيان ويحيى بن يمان لا يحتج بحديثه لسوء حفظه وكثرة خطئه
