Dr. Zakir: The fast can be broadly categorized into Fard fast that are obligatory and other is the 'tatau' fast i.e. the voluntary fast or the non-obligatory fast which InshaAllah we'll be dealing may be on the episode 31. <br /> <br />As far as the obligatory fast are concerned you can classify it under 4 types. <br /> <br />The first as we are discussing the obligatory fast during the month of Ramadhaan. <br /> <br />The second is if a person misses the fast of Ramadhaan for any reason, cover up the fast missed, its known as Qadha fast. <br />The third is fasting fro expiation of the sins. If you have committed a sin and you have to fast give a Kaffara. That is the third type. And the fourth is fasting if you are vowed to fast. So these are basically the 4 types of Fard fasting which are there in Islam.
