Kindly reference the following link(s):
Difference between Mani (Semen) and Mathi (Urethral fluid)
Characteristics of Mathi and Mani, cannot differentiate
Ruling on types of discharges: Mathi, Wadi, Mani, Regular vaginal discharge, Urine
When should one check their underwear when they feel Mathi (Precum) is discharged?
I always check before praying if I have emitted Prostatic fluid, Madhiy, is this ok?
