مَن كَانَ عَدُوًّا لِّلَّهِ وَمَلَـٰٓئِكَتِهِۦ وَرُسُلِهِۦ وَجِبْرِيلَ وَمِيكَىٰلَ فَإِنَّ ٱللَّهَ عَدُوٌّ لِّلْكَـٰفِرِينَ

Whoever is an enemy to Allāh and His angels and His messengers and Gabriel and Michael - then indeed, Allāh is an enemy to the disbelievers.

Al-Baqarah 98

۞ فَلَمَّآ أَحَسَّ عِيسَىٰ مِنْهُمُ ٱلْكُفْرَ قَالَ مَنْ أَنصَارِىٓ إِلَى ٱللَّهِ ۖ قَالَ ٱلْحَوَارِيُّونَ نَحْنُ أَنصَارُ ٱللَّهِ ءَامَنَّا بِٱللَّهِ وَٱشْهَدْ بِأَنَّا مُسْلِمُونَ

But when Jesus felt [persistence in] disbelief from them, he said, "Who are my supporters for [the cause of] Allāh?" The disciples said, "We are supporters for Allāh. We have believed in Allāh and testify that we are Muslims [submitting to Him].

Ali 'Imran 52

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَطِيعُوا۟ ٱللَّهَ وَأَطِيعُوا۟ ٱلرَّسُولَ وَأُو۟لِى ٱلْأَمْرِ مِنكُمْ ۖ فَإِن تَنَـٰزَعْتُمْ فِى شَىْءٍ فَرُدُّوهُ إِلَى ٱللَّهِ وَٱلرَّسُولِ إِن كُنتُمْ تُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ ۚ ذَٰلِكَ خَيْرٌ وَأَحْسَنُ تَأْوِيلًا

O you who have believed, obey Allāh and obey the Messenger and those in authority among you. And if you disagree over anything, refer it to Allāh and the Messenger, if you should believe in Allāh and the Last Day. That is the best [way] and best in result.

An-Nisa 59

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ أَطِيعُوا۟ ٱللَّهَ وَرَسُولَهُۥ وَلَا تَوَلَّوْا۟ عَنْهُ وَأَنتُمْ تَسْمَعُونَ

O you who have believed, obey Allāh and His Messenger and do not turn from him while you hear [his order].

Al-Anfal 20

تَٱللَّهِ لَقَدْ أَرْسَلْنَآ إِلَىٰٓ أُمَمٍ مِّن قَبْلِكَ فَزَيَّنَ لَهُمُ ٱلشَّيْطَـٰنُ أَعْمَـٰلَهُمْ فَهُوَ وَلِيُّهُمُ ٱلْيَوْمَ وَلَهُمْ عَذَابٌ أَلِيمٌ

By Allāh, We did certainly send [messengers] to nations before you, but Satan made their deeds attractive to them. And he is their [i.e., the disbelievers] ally today [as well], and they will have a painful punishment.

An-Nahl 63
