To cool themselves with water after

Q 1 : A man used miswak (tooth stick) while fasting, and then thinking that he had broken his fast, drank and ate afterwards. Is it obligatory upon him to make up for this fast and offer expiation, or (is it sufficient) just to make up for the fast?

A1 : Whoever breaks the fast during Ramadan, thinking that the use of the miswak breaks the fast, must make up for this fast, repent to Allah and seek forgiveness from Allah; perhaps Allah will forgive them.May Allah grant us success. May Allah send blessings and peace upon our Prophet Muhammad, upon his family and Companions!
