Mukhtasar Bukhari

Jabir bin Abdullah (may Allah be pleased with him) narrates that Abu Humayd Ansari brought milk to the Prophet (peace be upon him) in a bowl from the place of Naqi’. The Messenger of Allah (peace be upon him) said to him: “Why did you not cover it? (At least) you could have placed a broad wooden board over it.”

Narrated from Sayyiduna Abu Huraira (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The best charity is to give a she-camel with abundant milk to someone (in the way of Allah) to drink its milk, and likewise to give a goat with abundant milk, so that it fills one vessel with milk in the morning and another in the evening."
