The Importance Of Islam's Five Fundamentals

If a person denies, disbelieves, refuses, makes fun of or flouts one of the five fundamentals of Islam, he becomes a disbeliever, may Allah protect us! Similarly, he who does not accept any of the things which are unanimously and clearly declared as halal (permitted) or haram (forbidden), or who says halal for haram or haram for halal, becomes a disbeliever. If a person denies or dislikes one of the inevitably known Islamic teachings, that is, teachings that are heard and known even by the common people living in Muslim countries, he becomes a disbeliever. If an ordinary person does not know the teachings One should not be deceived by the false assertions of British spies and of those ignoramuses who have been trapped by them who say that there was no covering before the coming of the ayat of hijab and who say that fiqh [1] scholars have fabricated the command for covering later. If a person professes Islam, he has to know whether something he does is compatible with the Shari'at [2]. If he does not know, then he has to learn by asking a scholar of Ahl as-sunnat [3] or by reading books written by scholars in this category. If his action violates the Shari'at, he will not be exempted from the sin or heresy caused by that action. He has to make tawba daily in the true sense. When tawba is made, the sin or heresy (caused by that action) will definitely be forgiven. If he does not make tawba (repentace), he will pay for it both in the world and in hereafter.

[1] fiqh: knowledge dealing with what Muslims should do and should not do; actions, a'mal, 'ibadat.
[2] Shari'at: (pl. of Shari'a) i) rules and commandments as a whole of the religion. ii) religion.
[3] Ahl as-Sunna (wa'l-Jama'a): the true pious Muslims who follow as-Sahabat al-kiram. These are called Sunni Muslims. A Sunni Muslim adapts himself to one of the four Madhhabs. These madhhabs are Hanafi, Maliki, Shafi'i and Hanbali.
