Hadith 11:211
Muhammad ibn Bishr narrated to us, from Sadaqah ibn al-Muthanna, who said: I heard my grandfather, Rabah ibn al-Harith, mentioning from Sa'id ibn Zayd ibn 'Amr ibn Nufayl, who said: "By Allah, a scene that one of them witnesses for a single day in the path of Allah with the Messenger of Allah, in which his face becomes dusty, is better than the deeds of one of you, even if he were to live the lifespan of Noah."
