When a professor of the comparative religion gives his lecture, he speaks in a way superior to all religion, and starts to criticize the various religions; he does not belong to any religion; he only displays the various concepts of various religions. He has no doctrine at least during his lecture. This attitude will give him some pride and self satisfaction.
Many men here have given their opinion about religion, in the way a professor of comparative religion gives his lecture.
They say man invented the religion: primitive at the start, then the religion that man invented became more complicated.And then the atheism appeared which is more advanced than the religion that man invented; this is according to their imagination of the matter.
But what do they say when man in fact did not invent the religion? And that God – be glorified – sent His envoys: the apostles to warn man of the consequences of the association with God?
This is the religion of God: God is One without associate; this is from the start; and there were many variations according to distortion of this religion of God by different factors.
This is in the Quran 2: 213
كَانَ النَّاسُ أُمَّةً وَاحِدَةً فَبَعَثَ اللّهُ النَّبِيِّينَ مُبَشِّرِينَ وَمُنذِرِينَ وَأَنزَلَ مَعَهُمُ الْكِتَابَ بِالْحَقِّ لِيَحْكُمَ بَيْنَ النَّاسِ فِيمَا اخْتَلَفُواْ فِيهِ وَمَا اخْتَلَفَ فِيهِ إِلاَّ الَّذِينَ أُوتُوهُ مِن بَعْدِ مَا جَاءتْهُمُ الْبَيِّنَاتُ بَغْيًا بَيْنَهُمْ فَهَدَى اللّهُ الَّذِينَ آمَنُواْ لِمَا اخْتَلَفُواْ فِيهِ مِنَ الْحَقِّ بِإِذْنِهِ وَاللّهُ يَهْدِي مَن يَشَاء إِلَى صِرَاطٍ مُّسْتَقِيمٍ
The explanation:
(People were one nation [of monotheists, following one doctrine: at the time of Adam, then they deviated from the monotheism and associated some other things or beings with God],
and God sent prophets with the glad tidings and the warning, and sent down the [Heavenly] Scripture with them, indicating the true [religion];
that the [prophet] might judge people concerning their deviation [from monotheism];
but none deviated therefrom save those [religious leaders] given the [Scripture] even after the manifest [signs] had come to them, due to their 'greed and their wronging each other';
so God, with His permission [He gives permission to His angels to inspire the kind-hearted], guided the believers to the truth from which they deviated;
for God guides whom He pleases to a standard path [of monotheism.] )
