Riyad as-Salihin — Hadith #45948

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) forbade blowing in the drink, and a man said: I see it in the vessel?‏ He said, ‘I’m not telling you of one breath.’‏ He said, ‘The son of the mug is about you.’ Narrated by Al-Tirmidhi))
