Hadith 22295

Yahya related to me from Malik that Zayd ibn Aslam said, ''Umaribn al Khattab drank some milk which he liked (very much) and he askedthe man who had given it to him, 'Where did this milk come from?' Theman told him that he had come to a watering-place, which he named, andhad found grazing livestock from the zakat watering there. He wasgiven some of their milk, which he then put into his water-skin, andthat was the milk in question. Umar ibn al-Khattab then put his handinto his mouth to make himself vomit."Malik said, "Theposition with us is that if anyone refuses to honour one of theobligatory demands of Allah, and the muslims are unable to get it,then they have the right to fight him until they get itfrom him."
