To further explain Question and Answer # 21, I quote from The Noble Quran,
Chapter 2 Sura Al-Baqara, verse (78) And there are among them (Jews) unlettered people who know not the Book, but they trust upon false desires and they but guess.
وَمِنۡہُمۡ أُمِّيُّونَ لَا يَعۡلَمُونَ ٱلۡكِتَـٰبَ إِلَّآ أَمَانِىَّ وَإِنۡ هُمۡ إِلَّا يَظُنُّونَ (٧٨
Islam is an extension of the previous two religions Jewish and Christianity. So in Quran what ever general deeds as a nation are appreciated about these two previous religions, are appreciated in Islam too. And what ever general deeds as a nation are disliked about these two religions in Quran, are disliked in Islam too.
The above verse 78 of Chapter 2 Sura Al-Baqara, tells that the common population of Jews did not have access to their Holy Book (Torah). Torah was not available to common individuals to read so they did not know what Torah preached. Torah was written in Hebrew which was an obsolete language and was kept safe in Synagogues by Rabbis. Common people had to go to Rabbis if a problem arose in their lives. Therefore most of the time common individuals could not practice Devine Laws written in Torah the Holy Book and so the common people made important decisions of their lives by just guess work and by their own false desires thinking those decisions as correct, which were then seconded by their Rabbis. In this verse 78, Allah calls all those individuals, ‘illiterate people’ who do not know His Devine Books, The Scriptures.
It means what ever profession a person may have and what ever worldly education a person may have but if he does not know the Holy Book, Allah’s Book, the Scriptures, he stands in Allah’s Eyes, as an illiterate (uneducated, uninformed and ignorant) person. It is compulsory for a Muslim to get all kinds of educations of the world. From all the knowledges of the world, a Muslim’s foremost duty is, to know The Holy Quran, not once, not twice in his life time, but continously again and again, repeatedly so that he must be thorough in Quran all the time. This in turn makes him morally responsible not to falter at any time, his entire life. An educated person in Allah’s Eyes is the one who knows and understands His Sub Han Wa Ta’ala’s Holy Book Quran. In Islam a Muslim is literate when he knows and understands Quran what may his profession or worldly education be. For a Muslim understanding Quran is a must. May Allah make it easy for us all Muslims to understand and practice Quran. Aameen.
