All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
As long as the time of discontinuity of the vaginal discharges is unknown in which it gets longer or shorter, and advance or delay, then the ruling that applies to you is the same as that of the person who suffers from incontinence. Thus, perform ablution after the prayer time begins, perform the circumambulation (Tawaf), pray the obligatory prayer and whatever you want from supererogatory prayer until that time expires.
For more benefit on vaginal discharges, please refer to Fatwa 413527, 450682, 429052, 409849, 370681 and 367930.
