Madmadah for the fasting person

Q 1: I was pregnant and the weather was very hot during Ramadan. My mouth became extremely dry, so I did Madmadah (rinsing the mouth) with cold water to moisten my mouth and lips but I was keen lest any water should enter my stomach. Am I sinful? Should I offer a Kaffarah (expiation) for that?

A: According to what you have said, there is no sin on you and you do not need to make up for that day in which you did Madmadah with water because this does not invalidate one's Sawm (Fast).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
