Q: In the morning when I wake and I found a stain of dry white substance/dry white spot of fluid on my clothes not due to desire of sex, orgasm, and with no other sexual feelings. Is ghusl (bath) fardh (compulsory)?
If after I urinate a thick white discharge falls on the clothes is wudhu required?
A: In both case the thick white discharge will not make ghusl faradh. You will only need to make wudhu.
And Only Allah knows best
