As of now, yes -though it was not always this way. Islam used to be a rather comparitively progressive force when it was first founded, and women were often treated worse in the old Arab pagan traditions, and in surrounding societies that Arabs came across like those of the Persians. Only after Islam absorbed the customs of the societies that it came across did Muslim women came to be as oppressed as they are now throughout the Middle East and in Central Asia.
For anyone who wants to read about the status and lives of women in Islamic societies, I strongly recommend reading Geraldine Brooks'
Nine Parts of Desire: the Hidden World of Islamic Women. It is an eye-opener.
