And Ishaq ibn Mansur narrated to me; al-Nadr ibn Shumayl narrated to us; Shu'bah informed us, from al-Hakam, who said: I heard Dharr, from Ibn 'Abd al-Rahman ibn Abza, who said: al-Hakam said—and I had indeed heard it from Ibn 'Abd al-Rahman ibn Abza, from his father—that a man came to 'Umar and said, "I have become junub and found no water." And he related the hadith, adding in it: 'Ammar said, "O Commander of the Faithful, if you wish, by the right that Allah has made incumbent upon me toward you, I will not relate this to anyone." And he did not mention "Salamah narrated to me from Dharr."
