(Second chain) Sayyiduna Abu Humayd Sa'idi (may Allah be pleased with him) reported that he brought a bowl of milk from the place of Naqi' to the Prophet Muhammad (peace and blessings be upon him), which was not covered. The Prophet (peace and blessings be upon him) said: Why did you not cover it, even if you had placed a stick over it? Abu Humayd (may Allah be pleased with him) narrated that the Prophet (peace and blessings be upon him) commanded that the mouths of water skins be tied with a strap and that doors be kept closed at night. Zakariya, the narrator, did not mention the words "at night."
