Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Salim that Hazrat Umar sent Hazrat Aslam with the zakat camels towards the place of Huma. He says that when I was about to return, he (Umar) said, "Present them before me." I presented them in such a state that my luggage was on one of the she-camels. He (Umar), in anger, said, "May your mother be bereft of you! I intended that through this she-camel, the households of the Muslims would be sustained, and you loaded your own luggage on her. Was there not a camel that urinates a lot, or a she-camel that gives little milk (for this purpose)?"
