Yusuf Ali's Koranic translation has 25 verses with the word 'ignorant' in them. Most of these refer to the hated Kufar, or non-Muslim 'Unbeliever'. Najasun and Rijsun usually reference ignorance but they also identify people or things which are dirty, such as Jews, or unclean, non-Halal meat. There is no tolerance within the Koran for non-Muslims. In fact the cult's chief document is nothing else other than a very deranged and imperialist view of the Kufar. Najasun and Rijsun are just extensions of other execrable categorizations which label non-Muslims as unclean, unjust, stupid, hypocritical, evil and possessed by little devils. It is hard, nay impossible, to fashion a system of ethics and religiosity around such ideals. Islam is a cult, not a religion.
A cult has many elements but the following can are consistent with any cult development anywhere at any time in human history, including modern day secularist cults. There must be a worship of a 'great man' and leader; the division of the world into us versus them; the demonization of the 'other'; the depiction of non-cult members as stupid, evil, ignorant and wayward; and threats of hell or some punishment to any in the cult who will deny the cult's dogmas or rituals. Islam is a cult since it obviously uses all of these tools and plenty more in establishing a blind and very ignorant obedience to the cult's demands.
Obey the Great Leader
And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular Prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless. ( ???? ??????? , Al-Ahzab, Chapter #33, Verse #33)
Note: Allah is of course the alter-ego of Muhammad the supposed 'Messenger'.
Najasun Infidels are untermenschen or inferiors
009:028 O you who believe (in Allah's Oneness and in His Messenger (Muhammad SAW)! Verily, the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah, and in the Message of Muhammad SAW) are Najasun (impure). So let them not come near Al-Masjid-al-Haram (at Makkah) after this year, and if you fear poverty, Allah will enrich you if He will, out of His Bounty. Surely, Allah is All-Knowing, All-Wise.
Rijsun or Infidels will go to Hell
009:095 They will swear by Allah to you (Muslims) when you return to them, that you may turn away from them. So turn away from them. Surely, they are Rijsun [i.e. Najasun (impure) because of their evil deeds], and Hell is their dwelling place, - a recompense for that which they used to earn.
Infidel Rijsun – Jews and Christians -- cannot be trusted
3:75 Among the People of the Book are some who, if entrusted with a hoard of gold, will (readily) pay it back; others, who, if entrusted with a single silver coin, will not repay it unless thou constantly stoodest demanding, because, they say, "there is no call on us (to keep faith) with these ignorant (Pagans)." but they tell a lie against Allah, and (well) they know it. ( ???? ?? ????? , Aal-e-Imran, Chapter #3, Verse #75)
Infidel Ignorants ignore the 'truth' of Islam
6:11 Even if We did send unto them angels, and the dead did speak unto them, and We gathered together all things before their very eyes, they are not the ones to believe, unless it is in Allahs plan. But most of them ignore (the truth). ( ???? ??????? , Al-Anaam, Chapter #6, Verse #111)
48:26 While the Unbelievers got up in their hearts heat and cant - the heat and cant of ignorance,- Allah sent down His Tranquillity to his Messenger and to the Believers, and made them stick close to the command of self-restraint; and well were they entitled to it and worthy of it. And Allah has full knowledge of all things. ( ???? ????? , Al-Fath, Chapter #48, Verse #26)
Arab Pagans who reject Muhammad's cult are Najasun
9:97 The Arabs of the desert are the worst in Unbelief and hypocrisy, and most fitted to be in ignorance of the command which Allah hath sent down to His Messenger. But Allah is All-knowing, All-Wise. ( ???? ?????? , At-Taubah, Chapter #9, Verse #97)
Moslems will wail that this is all 'trickery' and mis-translation. That is a lie. All translations which are reputable will reveal the same message and verbiage. Cults are not religions since they deny the attributes of freedom. A religion after all frees its people and their bodies, minds, rationalities and spirits. Islam enslaves. It demands that its members are unthinking knaves. It promotes superstition, racism, supremacism and raging hatred. There is no Golden Rule within Islam. The above are just a very small sample as to why that fact is so obvious and undeniably apparent within Islamic theology.
