The Holy Quran is the book of guidance from Allah (SWT) and it has everything in it. It gives the solution to the mankind about their problems. The Holy Quran, Hadith and Fiqh are the sources one must consult in order to practice Islam.
The radical Islam or Islamic fundamentalism is a very confused term. There is vagueness in these terms. Let’s explore the terms.
The literal meaning of Radical Islam is that the version of Islam which is based purely on the Quran and Hadith, same applies to Islamic fundamentalism. Islamic fundamentalism is principally a term that refers to explain religious ideologies seen as promoting a return to the “fundamentals” and basics of Islam and the fundamentals of Islam is the Quran and the Sunnah.
The term is different for Muslims and it is altogether different for the anti Muslims. the Muslims think that Islamic fundamentalism means practicing Islam according to the Quran and Sunnah which includes Quran recitation, Salah(Prayer), Hajj (Pilgrimage) , Zakaat, etc.
The anti Muslims think that Islamic fundamentals are too strict to follow and there are two categories in Muslims, one the hardliners and other the liberals. The hardliners are the ones who are fundamentalists because they “follow the Quran and Hadith”.
The west world doesn’t not promote the “fundamentalists” because they are the ones who threat the west world. in actual Islam is the religion of peace and harmony, Quran recitation tells us that there is no compulsion in religion, as Allah (SWT) says in the Holy Quran : “Let there be no compulsion in religion: Truth stands out clear from Error: whoever rejects evil and believes in Allah hath grasped the most trustworthy hand-hold, that never breaks. And Allah heareth and knoweth all things”.
