Sayyiduna Munib al-Azdi (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) in the time of Jahiliyyah, saying to the people: "Say: There is no true god except Allah, and you will be successful." Some of them spat in his (peace and blessings be upon him) face, some threw dust upon him, and some reviled him, until half of the day had passed. Then a girl came with a vessel of water, and he (peace and blessings be upon him) washed his face - or his hands - and said: "O my daughter! Fear neither poverty nor humiliation for your father." I asked: Who is she? The people said: She is Zaynab, the daughter of the Messenger of Allah (peace and blessings be upon him), and she was a beautiful girl.
