أَلَمۡ تَرَ أَنَّ ٱللَّهَ 
یُولِجُ ٱلَّیۡلَ فِی ٱلنَّهَارِ وَیُولِجُ ٱلنَّهَارَ فِی ٱلَّیۡلِ وَسَخَّرَ ٱلشَّمۡسَ وَٱلۡقَمَرَۖ كُلࣱّ یَجۡرِیۤ إِلَىٰۤ 
أَجَلࣲ مُّسَمࣰّى 
وَأَنَّ ٱللَّهَ بِمَا 
تَعۡمَلُونَ خَبِیر
In this Surah, Tawhid is emphasized and Shirk and its ideas are critically examined. It tells us that those who are following Shirk they are only blindly following their forefathers. The true wisdom is to believe in Allah. The advises of Luqman the wise are also given here to support the same principles.
کیا تم نے نہیں دیکھا کہ 
خدا ہی 
رات کو دن میں داخل کرتا ہے اور (وہی) 
دن کو رات میں داخل کرتا ہے اور اُسی نے 
سورج اور چاند کو (تمہارے) زیر فرمان کر رکھا ہے۔ 

ہر ایک ایک وقتِ مقرر تک چل رہا ہے 
اور یہ کہ خدا تمہارے 
سب اعمال سے خبردار ہے
