Ubaydullah bin 'Abdullah bin 'Utba عبيد الله بن عبد الله بن عتبة بن مسعود · The Book of Adornment

"I heard the Messenger of Allah forbidding Al-Qaza' (shaving part of the head and leaving part)."

The Prophet said: "Whatever of the Izar comes below the ankles is in the Fire."

When the Prophet said what he said about the Izar, Umm Salamah said: "What about women?" He said: "Let it down a hand span." She said: "But then their feet will show." He said: "Then (let it down) a forearm's length, but no more than that."

"The Messenger of Allah was asked how much a woman should let her hem drag. He said: 'A hand span.' She said: 'But then it will uncover her (feet).' He said: 'A forearm's length, and no more than that.'"

"The Messenger of Allah forbade Ishtimal As-Samma' and wrapping oneself in a single garment (that did not cover the private parts)."
