The Prophet, may Allah's prayers and peace be upon him, recommended fasting three days of every month, which are the thirteenth, fourteenth, and fifteenth days, due to their benefits, including: removing rancor from the chest, being equivalent to perpetual fasting, and curbing desires. Some doctors mention that fasting expels waste products that accumulate in the body due to humidity on these days.
