It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that once we were on a journey with the Noble Prophet (peace and blessings be upon him). We were covered in dust and shaking it off when we passed by some camels whose udders were tied and they were grazing among the trees. People hurried forward to milk them. The Noble Prophet (peace and blessings be upon him) said to them: "It is possible that the livelihood of a Muslim household depends only on this. Would you like that they come to your provision bag and take everything that is in it?" Then he said: "If you must do something, then only drink (from it), but do not take anything with you."
