61ٱللَّهُ ٱلَّذِى جَعَلَ لَكُمُ ٱلَّيْلَ لِتَسْكُنُوا۟ فِيهِ وَٱلنَّهَارَ مُبْصِرًا ۚ إِنَّ ٱللَّهَ لَذُو فَضْلٍ عَلَى ٱلنَّاسِ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَشْكُرُونَ
62ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ خَـٰلِقُ كُلِّ شَىْءٍ لَّآ إِلَـٰهَ إِلَّا هُوَ ۖ فَأَنَّىٰ تُؤْفَكُونَ
63كَذَٰلِكَ يُؤْفَكُ ٱلَّذِينَ كَانُوا۟ بِـَٔايَـٰتِ ٱللَّهِ يَجْحَدُونَ
[61-63] It is Allah Who made the night for you to rest in it, and made the day bright. The fact is that Allah is highly Bounteous to the people, yet most people are not thankful.85 The same Allah (Who has done all this for you) is your Lord, the Creator of everything. There is no god but He.86 Whence then are you being deluded?87 Likewise were all those people deluded, who denied the Revelations of Allah.88
85This verse comprises two important themes: First, the night and the day have been presented in it as an argument for Tauhid, because their alternating regularly means that One God alone is ruling over the earth and the sun, and their alternation's being beneficial for man and other earthly creatures is an express proof of the fact that the same One God is also the Creator of all these things and has devised this system with such great wisdom that it should be beneficial and useful for all His creatures. Secondly, in this verse the atheists and the polytheists have been to realize how great a blessing has Allah bestowed on them in the shape of the night and the day and what ungrateful wretches they are that while they are benefiting from this blessing of His they are being disloyal and rebellious to Him day and night (For father explanation see Yunus 87,Alfurqan 62, E.N.'s thereof).
86That is, "The alternation of the night and day has proved that Allah alone is your Creator as well as of everything else, and the great advantage and benefits that accrue from this alternation for your life, prove that He is your highly Beneficent Lord. After this, it automatically follows that He is your real Deity too. For it would be wholly against reason and justice that your Creator and Providence should be Allah and your deities others."
87That is, "Who is misleading you to think that those who are neither the creators nor providers should deserve to be worshiped by you?"
88That is, "In every age the common people have been deluded by the misguides only because the people did not believe in the Revelations that Allah sent down through His Messengers to make them understand the Truth. Consequently; they were trapped by the selfish, dishonest people, who had set up shrines of false gods as a business. "
