Allah سبحانه وتعالى said,

أَلَمْ تَرَ إِلَى الَّذِينَ تَوَلَّوْاْ قَوْماً غَضِبَ اللَّهُ عَلَيْهِم مَّا هُم مِّنكُمْ وَلاَ مِنْهُمْ وَيَحْلِفُونَ عَلَى الْكَذِبِ وَهُمْ يَعْلَمُونَ - أَعَدَّ اللَّهُ لَهُمْ عَذَاباً شَدِيداً إِنَّهُمْ سَآءَ مَا كَانُواْ يَعْمَلُونَ - اتَّخَذْواْ أَيْمَـنَهُمْ جُنَّةً فَصَدُّواْ عَن سَبِيلِ اللَّهِ فَلَهُمْ عَذَابٌ مُّهِينٌ - لَّن تُغْنِىَ عَنْهُمْ أَمْوَلُهُمْ وَلاَ أَوْلَـدُهُمْ مِّنَ اللَّهِ شَيْئاً أُوْلَـئِكَ أَصْحَـبُ النَّارِ هُمْ فِيهَا خَـلِدُونَ

“Have you not seen those who take as allies a people upon whom is the wrath of Allah They are neither of you nor of them, and they swear to a lie while they know. Allah has prepared for them a severe torment. Evil indeed is that which they used to do. They have made their oaths a screen. Thus they hinder (others) from the path of Allah, so they shall have a humiliating torment. Their children and their wealth will avail them nothing against Allah. They will be the dwellers of the Fire to dwell therein forever.”

[Surah al-Mujadilah 58:14-17]

The Messenger of Allah صلى الله عليه و سلم said:

عِصَابَتَانِ مِنْ أُمَّتِي أَحْرَزَهُمَا اللَّهُ مِنْ النَّارِ عِصَابَةٌ تَغْزُو الْهِنْدَ وَعِصَابَةٌ تَكُونُ مَعَ عِيسَى ابْنِ مَرْيَمَ عَلَيْهِمَا السَّلَام

"Allah will protect two groups of my Ummah from the Fire: a group that will Open Hind, and a group that will be with Esa ibn Maryam عليه السلام."

An-Nisa'i, Ahmad
