Is the moisture from a woman's private parts pure?

The Shaykh : Based on this, the moisture from a woman's private parts differs between what comes from the vaginal canal and what comes from the urethra, because the private parts, by the permission of Allah, have two passages. The passage of the vaginal canal is connected to the uterus and has no connection to the bladder or the urinary tract at all; it exits from the lower part of the private parts. The other passage is the urethra, which is at the upper part of the private parts and is the one connected to the bladder. If this moisture results from a relaxation of the bladder and comes from the urethra, it is ritually impure, and its ruling is the ruling of urinary incontinence. If this moisture comes from the vaginal canal, it is ritually pure, because it is not from the waste of food and drink, but rather it comes from this passage in which Allah the Exalted placed this fluid for a wisdom He wills, so it is pure.
