Is it obligatory to perform ablution (wudu') due to excessive vaginal discharge that exits involuntarily, given that it may lead to missing prayers when outside the home?

If you suffer from perpetual discharge, perform ablution for each prayer after its time has begun, and pray with your ablution as many obligatory and supererogatory prayers as you wish until the time expires. You are not required to purify these discharges because they are pure. If performing ablution for each prayer is difficult for you, then it is permissible for you to adopt the view of the Maliki school, who believe that ablution is not invalidated by perpetual ritual impurity. However, do not abandon prayer under any circumstances.
