From the Prophet’s noble character was his gracious forbearance: he never disparaged any food that was set before him, for food is one of Allah’s blessings upon His servants. If he desired it, he ate; if he did not, he simply left it.
The two Sahihs relate from Ibn ʿAbbas: “The Prophet ﷺ entered the house of Maymunah and a dhabb (spiny-tailed lizard) was offered to him. He reached out his hand to take it, whereupon one of the women present said, ‘Tell the Messenger of Allah what you have served him.’ They said, ‘It is a dhabb, Messenger of Allah.’ He withdrew his hand. Khalid ibn al-Walid then asked, ‘Is it unlawful, Messenger of Allah?’ He replied, ‘No, but it is not found in the land of my people, and I do not feel inclined toward it.’ So Khalid pulled it toward himself and ate it.”
Muslim also records from Jabir: “The Prophet ﷺ entered one of the apartments of his wives and asked, ‘Do you have any relish (idām)?’ They said, ‘Nothing but a little vinegar.’ He said, ‘Bring it, for what an excellent relish it is!’”

It is prohibited to breathe into the vessel. Doing so soils the vessel and the drink for whoever drinks after the one who breathed into it; it also means breathing and swallowing at the same time, which may cause choking. Moreover, drinking in three separate breaths while taking the cup away from the lips is easier, more pleasant, and more wholesome. The purified Islamic law commands only what brings benefit and forbids only what brings harm and evil.
