<b>Guidance from the Hadiths:</b><br> 1) Fasting three days every month is equivalent to fasting the whole year, for a good deed is rewarded by ten times as much.<br> 2) Fasting the three days in the middle of the month - 13, 14, and 15 - is the best form of fasting, for this was the more frequent practice of the Prophet (may Allah’s peace and blessings be upon him).<br> 3) They show the merit of the Companions, as they were keen to act upon the Prophet’s instructions throughout their lives.
