The gravity of not fasting one day of Ramadhan without a valid reason

Fasting in Ramadhan is Fardh (compulsory) upon every Muslim who is major and sane. One must not neglect a fast without a valid reason because doing so is a grave sin.

According to the Hadith, a fast in the month of Ramadhan that has been missed without a valid reason cannot be replaced even if the person fasts his entire life. That is why, as far as possible, we should not miss any fast. However, if we happen to miss a fast, then, we must replace it at all cost.

It is even more serious to break a fast of Ramadan without a valid reason. Let alone the sin and the punishment for this action, the Kaffarah (compensation) itself for the intentionally broken fast without a reason, is very severe. The Kaffarah for this broken fast is that the person has to fast 60 days consecutively in addition to replacing the broken fast!
