(Fatwa: 621/495/N=6/1439)
The vaginal discharge of white, thick and foul odour seems to be leucorrhoea and on discharging it only wudhu breaks and it does not make ghusl wajib. Thus if after getting up you do not remember having any dream and you are sure that this is leucorrhoea then in such a case ghusl will not be fardh on you. Just wash the leucorrhoea smeared on your body or cloth and make wudhu and offer salah. You need worry not and have any doubt.
مستفاد: ولا يجب اتفاقاً فيما إذا علم أنه ودي مطلقاً، وفيما إذا علم أنه مذي أوشك فى الأخيرين مع عدم تذكر الاحتلام (رد المحتار، كتاب الطهارة، 1: 301، ط: مكتبة زكريا ديوبند).
Allah knows Best!
