Not exposing one's sins

Q: I wanted to ask which sin is lesser of the two evils, exposing one's sin or lying? I am asking because if someone asks if you have comitted a sin, is it permissible to lie and say you haven't? Would that be better than exposing your sin? In a situation where you cannot avoid the question?

Discharge breaking wudhu

Q: At any time of the day there is an amount of clear, odourless discharge. This is regardless of whether I am pregnant or not. I do not feel anything coming out. It doesn’t leave any stain at all. If I am not mistaken, Muftionline has said that all types of discharge are not paak and break wudhu.

Can Mufti Saheb please explain this again if possible. Many women are finding it to be very difficult as we don’t know when this emerges and it is something that is always there if we have to check inside. Could it be a type of perspiration that cleanses the area and keeps it from drying out? 

Finding the qiblah on a ship

Q: I am working on a ship for 6 months at a time. Sometimes we go from America to China and I cannot find the qibla. On sea, our normal application does not work properly so it is difficult to find the qibla. I am performing salaah without knowing qibla direction. Is it permissible?
