The Quran

قُل هَل مِن شُرَكائِكُم مَن يَهدي إِلَى الحَقِّ ۚ قُلِ اللَّهُ يَهدي لِلحَقِّ ۗ أَفَمَن يَهدي إِلَى الحَقِّ أَحَقُّ أَن يُتَّبَعَ أَمَّن لا يَهِدّي إِلّا أَن يُهدىٰ ۖ فَما لَكُم كَيفَ تَحكُمونَ

Muhammad Asad

Say: "Does any of those beings to whom you ascribe a share in God's divinity guide unto the truth?" Say: "It is God [alone] who guides unto the truth. Which, then, is more worthy to be followed - He who guides unto the truth, or he who cannot find the right way unless he is guided?¹ What, then, is amiss with you and your judgment?"²

Since the concept of "finding the right way" cannot apply to lifeless idols and idolatrous images, the above passage obviously relates to animate beings - whether dead or alive - to whom "a share in God's divinity" is falsely attributed: that is, to saintly personalities, prophets or angels whom popular fancy blasphemously endows with some or all of God's qualities, sometimes even to the extent that they are regarded as a manifestation or incarnation of God on earth. As for the act of God's guidance, it is displayed, primarily, in the power of conscious reasoning as well as of instinctive insight with which He has graced man, thus enabling him to follow the divine laws of right conduct (Zamakhshari).
Lit., "[and] how do you judge?"
