Uthman bin Abu al-As narrates that Sayyiduna Umar (may Allah be pleased with him) passed by the vessel of a man from the tribe of Thaqif and said: Bring me this nabidh. It was brought to him, and Sayyiduna Umar (may Allah be pleased with him) took it and found it to be strong. So Sayyiduna Umar (may Allah be pleased with him) said: Whoever finds sharpness in this nabidh should reduce its intensity with water.
