Ya-Sin - 36:22

وَمَا لِي لاَ أَعْبُدُ الَّذِي فَطَرَنِي وَإِلَيْهِ تُرْجَعُونَ
[36:22]
And what reason have I that I should not serve Him Who brought me into existence? And to Him you shall be brought back;
"It would not be reasonable in me if I did not serve Him Who created me, and to Whom ye shall (all) be brought back.
For what cause should I not serve Him Who hath created me, and unto Whom ye will be brought back?
