Placing a barrier between men and women in mosques

The questioner:
Honorable Shaykh, may Allah grant you success. He says: Some people say that placing a barrier or screen between men and women in mosques is a bid'ah (religious innovation), because the Prophet (peace and blessings be upon him) did not do it. Is their statement correct?

The Shaykh:
No, that is not correct. The barrier provides more privacy for the women. Privacy is what is required. It also relieves the women from the men looking at them and from the need for caution. So this is a good thing, yes, and it is not a bid'ah, yes.

The questioner:
Honorable Shaykh, may Allah grant you success.

The Shaykh:
But those who say this want to mix the women with the men. They deny the separation of the women and want them to pray with the men, right next to them. And they found nothing to object to except this issue, saying it is a bid'ah. So do they deny bid'ah? No, they do not deny bid'ah, but they take this as a means to mix the women with the men and to look at the women. And we have not seen them deny bid'ah?
