Maududi commented:
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." (9.30)
Does anyone know the source for this hadith
