Does Release Of Madhi Removes Basic Taharat?
By fasting it meant at the start of fasting, if there is any need for cleaning, it should be done. Usually, such cleaning is done from time to time in normal course of day without any unnecessary delays, but when about to start an ibadah for which it is a condition, just an extra precaution to make sure one is clean. And then it is only natural if one stays extra conscious during the day ( this should not be confused with unnecessary doubts of impurity ).
