Al-An'am - 6:77

فَلَمَّا رَأَى الْقَمَرَ بَازِغًا قَالَ هَـذَا رَبِّي فَلَمَّا أَفَلَ قَالَ لَئِن لَّمْ يَهْدِنِي رَبِّي لأكُونَنَّ مِنَ الْقَوْمِ الضَّالِّينَ
[6:77]
Then when he saw the moon rising, he said: Is this my Lord? So when it set, he said: If my Lord had not guided me I should certainly be of the erring people.
When he saw the moon rising in splendour, he said: "This is my Lord." But when the moon set, He said: "unless my Lord guide me, I shall surely be among those who go astray."
And when he saw the moon uprising, he exclaimed: This is my Lord. But when it set, he said: Unless my Lord guide me, I surely shall become one of the folk who are astray.
