Does wind exiting a woman's front private part nullify wudu'?

Scholars have differed regarding the invalidation of ablution (wudu') by the emission of wind from a woman's front passage. The Shafi'is and Hanbalis hold that it invalidates ablution, while the Hanafis and Malikis believe it does not, considering it an unusual discharge. The more cautious approach is for a woman to perform ablution if she feels this wind has been emitted.
