The Prophet's wives have told us everything about his behavior in the privacy of his own home. There is not a single report that the Prophet ever rebuked any of his wives for any act of commission or omission. Even with his servants the Prophet was the kindest man. Visiting delegations to Madinah often thought that Anas and his mother belonged to the Prophet's own family, when they were only in his service. We tend to overlook all this and give little importance to the high-priority objective of Islam, namely, the eliminating of all injustice.
People treat their wives unjustly, and they are unjust to people in their employment.
Yet voices which speak against that remain faint, particularly of Muslim scholars. It is a fact of life that contemporary scholars have not addressed this question adequately. On the other hand, we have so much said and written about matters that cannot be described as being of equal importance. Look at the emphasis given to issues like the permissibility or otherwise of music, singing, photography, wearing a long robe that covers a man's ankles, etc. Look at the volume of spoken and written reminders on these and similar issues such as the length of a man's beard, the covering of a woman's face, the joining of people's feet in congregational prayer, etc.
