Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "The smell from the mouth of a fasting person is better in the sight of Allah than the fragrance of musk. For the fasting person there are two moments of joy: one at the time of breaking the fast, and the other at the time of joy on the Day of Resurrection." That is, when he will see the reward of fasting on the Day of Resurrection, he will be happy «كما فى البخاري» .
