وَقَالَ لَهُمْ نَبِيُّهُمْ إِنَّ ٱللَّهَ قَدْ بَعَثَ لَكُمْ طَالُوتَ مَلِكًا ۚ قَالُوٓا۟ أَنَّىٰ يَكُونُ لَهُ ٱلْمُلْكُ عَلَيْنَا وَنَحْنُ أَحَقُّ بِٱلْمُلْكِ مِنْهُ وَلَمْ يُؤْتَ سَعَةً مِّنَ ٱلْمَالِ ۚ قَالَ إِنَّ ٱللَّهَ ٱصْطَفَىٰهُ عَلَيْكُمْ وَزَادَهُۥ بَسْطَةً فِى ٱلْعِلْمِ وَٱلْجِسْمِ ۖ وَٱللَّهُ يُؤْتِى مُلْكَهُۥ مَن يَشَآءُ ۚ وَٱللَّهُ وَٰسِعٌ عَلِيمٌ

And their prophet said to them, "Indeed, Allāh has sent to you Saul as a king." They said, "How can he have kingship over us while we are more worthy of kingship than him and he has not been given any measure of wealth?" He said, "Indeed, Allāh has chosen him over you and has increased him abundantly in knowledge and stature. And Allāh gives His sovereignty to whom He wills. And Allāh is all-Encompassing [in favor] and Knowing."

Al-Baqarah 247

وَلَن تَرْضَىٰ عَنكَ ٱلْيَهُودُ وَلَا ٱلنَّصَـٰرَىٰ حَتَّىٰ تَتَّبِعَ مِلَّتَهُمْ ۗ قُلْ إِنَّ هُدَى ٱللَّهِ هُوَ ٱلْهُدَىٰ ۗ وَلَئِنِ ٱتَّبَعْتَ أَهْوَآءَهُم بَعْدَ ٱلَّذِى جَآءَكَ مِنَ ٱلْعِلْمِ ۙ مَا لَكَ مِنَ ٱللَّهِ مِن وَلِىٍّ وَلَا نَصِيرٍ

And never will the Jews and the Christians approve of you until you follow their religion. Say, "Indeed, the guidance of Allāh is the [only] guidance." If you were to follow their desires after what has come to you of knowledge, you would have against Allāh no protector or helper.

Al-Baqarah 120

ٱللَّهُ وَلِىُّ ٱلَّذِينَ ءَامَنُوا۟ يُخْرِجُهُم مِّنَ ٱلظُّلُمَـٰتِ إِلَى ٱلنُّورِ ۖ وَٱلَّذِينَ كَفَرُوٓا۟ أَوْلِيَآؤُهُمُ ٱلطَّـٰغُوتُ يُخْرِجُونَهُم مِّنَ ٱلنُّورِ إِلَى ٱلظُّلُمَـٰتِ ۗ أُو۟لَـٰٓئِكَ أَصْحَـٰبُ ٱلنَّارِ ۖ هُمْ فِيهَا خَـٰلِدُونَ

Allāh is the Ally1 of those who believe. He brings them out from darknesses into the light. And those who disbelieve - their allies are ṭāghūt. They take them out of the light into darknesses.2 Those are the companions of the Fire; they will abide eternally therein.

Al-Baqarah 257

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن تُطِيعُوا۟ ٱلَّذِينَ كَفَرُوا۟ يَرُدُّوكُمْ عَلَىٰٓ أَعْقَـٰبِكُمْ فَتَنقَلِبُوا۟ خَـٰسِرِينَ

O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers.

Ali 'Imran 149

إِذْ هَمَّت طَّآئِفَتَانِ مِنكُمْ أَن تَفْشَلَا وَٱللَّهُ وَلِيُّهُمَا ۗ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

When two parties among you were about to lose courage, but Allāh was their ally; and upon Allāh the believers should rely.

Ali 'Imran 122
