In what case should a female take ghusl janabat.
If the discharge is transparent or white? And what if it happens during fast in mahe ramadan? What about the liquid that is discharged while chatting or talking with fiance?

For ghusl e janabat to become wajib for a woman, she must reach orgasm (sexual satisfaction) and a fluid is discharged. According to Ayatollah Sistani, if just fluid is discharged (not at the time of sexual satisfaction) if the fluid is a lot, based on obligatory precaution, she has become junub and in this case she can refer to other scholars.
