Ibn Umar (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "There is no ihram upon a woman except in her face."
Abu Ahmad bin Adi (may Allah have mercy on him) said: I do not know anyone other than this Abu al-Jamal who narrates it from Ubaydullah as marfu' (attributed to the Prophet).
Ayyub bin Muhammad Abu al-Jamal is da'if (weak) according to the scholars of hadith; Yahya bin Ma'in and others declared him weak. This hadith has also been narrated from Ubaydullah bin Umar as marfu' through another, unknown (majhul) route, and what is preserved (mahfuz) is that it is mawquf (the statement of Ibn Umar).
