Musannaf Ibn Abi Shayba 1:892

Abu Bakr narrated to us, he said: Muhammad ibn Fudayl narrated to us, from Abu Sinan Dirar, from Muharib, from Ibn Umar, who said: "Whoever scoops from water while he is in a state of major ritual impurity (junub), then what remains of it is impure. And the angels do not enter a house in which there is urine."
