» Fard – Obligatory: An act commanded by Allah in the Holy
Qur’an is known as Fard. The following explains a Fard in
detail: a. An act that is obligatory to be executed b. It has
been proven by rigorously authenticated texts c. The denial of
any Fard renders one to come out of the folds of Islam. d. If
one omits to perform any Fard without any valid shari’i reason,
then such a person becomes a fasiq (transgressor) and the person
is regarded as a major sinner. [Fatawa Ridawiyyah – Vol. 2, Page
194] » Wajib – Necessary: An act that is almost as compulsory as
a Fard. The Messenger of Allah SallAllaho Alaihi wa Aalihi wa
Sallam never omitted it. It is a graded second, below a Fard in
its necessity. a. An act that is compulsory to do. b. It is
proven by religious arguments through ijtihad. c. One who denies
a Wajib is misguided. d. If one omits a Wajib without any valid
shari’i reason, then he is a transgressor and liable for the
punishment of Hell. e. To miss a Wajib once (deliberately,
without any valid reason)
