Israa,
First it is Dhulka Fiiq...not Fiikh, and the other one is dhulka Xaaq not duulka...
People who use the word FIIQ do not use it as peel because they use the word " Dhil" for peel.. so both of them are right...
Hannah,
The "xaaq" the lady used is not for the miscarriage... What she is talking about is the cleaning( I do not remember the right English term) of the miscarriage from the women's womb... Waxaa lasoo xaaqay waa dhiciska...
