Yazid ibn Harun narrated to us, he said: Muhammad ibn Ishaq narrated to us, he said: Sa'id ibn 'Ubayd ibn al-Sabbaq narrated to us, from his father, from Sahl ibn Hunayf, who said: I said, "O Messenger of Allah, what about what touches my garment from it?" He said, "It is sufficient for you to take a handful of water and sprinkle it over your garment where you see that it has touched."
