42:10
وَمَا ٱخْتَلَفْتُمْ فِيهِ مِن شَىْءٍ فَحُكْمُهُۥٓ إِلَى ٱللَّهِ ۚ ذَٰلِكُمُ ٱللَّهُ رَبِّى عَلَيْهِ تَوَكَّلْتُ وَإِلَيْهِ أُنِيبُ
And in anything over which you disagree - its ruling is [to be referred] to Allah. [Say], "That is Allah, my Lord; upon Him I have relied, and to Him I turn back."

وَلَوْ شَآءَ ٱللَّهُ لَجَعَلَهُمْ أُمَّةً وَٰحِدَةً وَلَـٰكِن يُدْخِلُ مَن يَشَآءُ فِى رَحْمَتِهِۦ ۚ وَٱلظَّـٰلِمُونَ مَا لَهُم مِّن وَلِىٍّ وَلَا نَصِيرٍ
And if Allah willed, He could have made them [of] one religion, but He admits whom He wills into His mercy. And the wrongdoers have not any protector or helper.
أَمِ ٱتَّخَذُوا۟ مِن دُونِهِۦٓ أَوْلِيَآءَ ۖ فَٱللَّهُ هُوَ ٱلْوَلِىُّ وَهُوَ يُحْىِ ٱلْمَوْتَىٰ وَهُوَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
Or have they taken protectors [or allies] besides him? But Allah - He is the Protector, and He gives life to the dead, and He is over all things competent.
فَاطِرُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ جَعَلَ لَكُم مِّنْ أَنفُسِكُمْ أَزْوَٰجًا وَمِنَ ٱلْأَنْعَـٰمِ أَزْوَٰجًا ۖ يَذْرَؤُكُمْ فِيهِ ۚ لَيْسَ كَمِثْلِهِۦ شَىْءٌ ۖ وَهُوَ ٱلسَّمِيعُ ٱلْبَصِيرُ
[He is] Creator of the heavens and the earth. He has made for you from yourselves, mates, and among the cattle, mates; He multiplies you thereby. There is nothing like unto Him, and He is the Hearing, the Seeing.
لَهُۥ مَقَالِيدُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۖ يَبْسُطُ ٱلرِّزْقَ لِمَن يَشَآءُ وَيَقْدِرُ ۚ إِنَّهُۥ بِكُلِّ شَىْءٍ عَلِيمٌ
To Him belong the keys of the heavens and the earth. He extends provision for whom He wills and restricts [it]. Indeed He is, of all things, Knowing.
