اتَّخَذُوا أَحْبَارَهُمْ وَرُهْبَانَهُمْ أَرْبَابًا مِّن دُونِ اللَّهِ وَالْمَسِيحَ ابْنَ مَرْيَمَ وَمَا أُمِرُوا إِلَّا لِيَعْبُدُوا إِلَٰهًا وَاحِدًا ۖ لَّا إِلَٰهَ إِلَّا هُوَ ۚ سُبْحَانَهُ عَمَّا يُشْرِكُونَ (31)
(9:31) They have made their scholars and monks as their Lords beside Allah, *31 and likewise the Messiah, the son of Mary, although they were enjoined not to worship any other than the One Deity, besides Whom there is none worthy of worship. He is absolutely pure and free from what they associate with Him.
*31) "They have taken their scholars and monks as their Lords the Holy Prophet himself explained its true significance. According to a Tradition, when Hadrat `Adi bin Hatim, who was formerly a Christian, came to the Holy Prophet with the intention of understanding Islam, he asked several questions in order to remove his doubts. One of these was: "This verse accuses us of taking our scholars and monks as our lords. What is its real meaning, sir? For we do not take them as our fords."
As a reply to this, the Holy Prophet put him a counter-question: "Is it not a fact that you accept as unlawful what they declare to be unlawful, and lawful what they declare to be lawful?" 'Adi confessed, "Yes, sir, it is so." The Holy Prophet replied, "This amounts to making them your lords." Incidentally, this Tradition shows that those who themselves set limits to the lawful and the unlawful without the authority of Allah's Book, assume for themselves the rank of Godhead, and those who acknowledge their right of making laws take them as their Lords.
It should be noted that they have been charged with (a) attributing sons to AIlah, and (b) giving the right of making laws to others than Allah. These are to prove that their claim, that they believed in Allah, is false, even though they should believe in his existence. But such a wrong conception of AIIah makes their belief in Allah meaningless.
