Say: "Shall we indeed call on others besides Allah,- things that can do us neither good nor harm,- and turn on our heels after receiving guidance from Allah? - like one whom the evil ones have made into a fool, wandering bewildered through the earth, his friends calling, come to us', (vainly) guiding him to the path." Say: "Allah's guidance is the (only) guidance, and we have been directed to submit ourselves to the Lord of the worlds;- 71 and to be constant in prayer and conscious of Him: for it is He unto whom you all shall be gathered." 72 It is He who created the heavens and the earth with a definite purpose. The day He will say "Be, " it will be. His word is the truth, His alone the power on the Day when the blast of the trumpet will be sounded. He knows the hidden and the visible. He is all-prudent and all-knowing. 73 ۞ Lo! Abraham said to his father Azar: "Takest thou idols for gods? For I see thee and thy people in manifest error." 74 And thus We showed Abraham the kingdom of the heavens and the earth, so that he might become one of those who have sure faith.. The adversaries are told that they can observe God's signs in the phenomena of the universe, just as Abraham could. The difference is that they see nothing, as if they were blind, whereas Abraham saw with open eyes. The sun, moon and stars which rise and set before their eyes day after day and night after night witness them as misguided at their setting as at their rising. Yet the same signs were observed by the perceptive Abraham, and the physical phenomena helped him arrive at the Truth. 75 So when the night covered him [with darkness], he saw a star. He said, "This is my lord." But when it set, he said, "I like not those that disappear." 76 When he saw the moon rising up, he said: "This is my lord." But when it set, he said: "Unless my Lord guides me, I shall surely be among the erring people." 77 When he saw the rising sun, he said, "This is my Lord for it is greater (than the others)." But when this too faded away, (Abraham) said, "My people, I disavow whatever you consider equal to God. 78 Indeed, I have turned my face toward He who created the heavens and the earth, inclining toward truth, and I am not of those who associate others with Allah." 79 His people argued with him. He said: Dispute ye with me concerning Allah when He hath guided me? I fear not at all that which ye set up beside Him unless my Lord willeth aught. My Lord includeth all things in His knowledge. Will ye not then remember? 80 How should I fear that which ye set up beside Him, when ye fear not to set up beside Allah that for which He hath revealed unto you no warrant? Which of the two factions hath more right to safety? (Answer me that) if ye have knowledge. 81 Those who have accepted the faith and have kept it pure from injustice, have achieved security and guidance. 82
