Tafsir Ibn Kathir -> Surah Fatir -> The Evidence of Tawhid

Allah shows His servants that they should worship Him Alone, for just as He is Independent in His power of creation and provision, so He should be worshipped Alone with no partners or associates such as idols and false gods. So Allah says:

﴿لاَ إِلَـهَ إِلاَّ هُوَ فَأَنَّى تُؤْفَكُونَ﴾

(La ilaha illa Huwa. How then are you turning away (from Him)) meaning, `how can you turn away from Him after this has been made clear and this proof has been made obvious, but you still worship idols and false gods' And Allah knows best.

﴿وَإِن يُكَذِّبُوكَ فَقَدْ كُذِّبَتْ رُسُلٌ مِّن قَبْلِكَ وَإِلَى اللَّهِ تُرْجَعُ الاٍّمُورُ - يأَيُّهَا النَّاسُ إِنَّ وَعْدَ اللَّهِ حَقٌّ فَلاَ تَغُرَّنَّكُمُ الْحَيَوةُ الدُّنْيَا وَلاَ يَغُرَّنَّكُمْ بِاللَّهِ الْغَرُورُ - إِنَّ الشَّيْطَـنَ لَكُمْ عَدُوٌّ فَاتَّخِذُوهُ عَدُوّاً إِنَّمَا يَدْعُو حِزْبَهُ لِيَكُونُواْ مِنْ أَصْحَـبِ السَّعِيرِ ﴾

(4. And if they deny you, so were Messengers denied before you. And to Allah return all matters.) (5. O mankind! Verily, the promise of Allah is true. So, let not this present life deceive you, and let not the chief deceiver deceive you about Allah.) (6. Surely, Shaytan is an enemy to you, so take (treat) him as an enemy. He only invites his followers that they may become the dwellers of the blazing Fire.)
