الجواب حامدا و مصلیا
According to the Shari’a, Fasting does not get effected due to the discharge of Mazi (pre-coitus discharge). However it nullifies Wudhu (Ablution) and it is necessary to repeat it. Further, if it happened to talk with non-Mehrem (members of opposite sex with whom marriage is permissible) to the extent of necessity, it should be only what is essential and it is Wajib (incumbent) to refrain from adopting mutual frankness and outspokenness beyond this.
