Al-Ma'idah 5:56

وَيَقُولُ الَّذِينَ آمَنُوا أَهَـٰؤُلَاءِ الَّذِينَ أَقْسَمُوا بِاللَّهِ جَهْدَ أَيْمَانِهِمْ ۙ إِنَّهُمْ لَمَعَكُمْ ۚ حَبِطَتْ أَعْمَالُهُمْ فَأَصْبَحُوا خَاسِرِينَ

And those who believe will say, "Are these the ones who swore by Allah their strongest oaths that indeed they were with you?" Their deeds have become worthless, and they have become losers.

يَا أَيُّهَا الَّذِينَ آمَنُوا مَن يَرْتَدَّ مِنكُمْ عَن دِينِهِ فَسَوْفَ يَأْتِي اللَّهُ بِقَوْمٍ يُحِبُّهُمْ وَيُحِبُّونَهُ أَذِلَّةٍ عَلَى الْمُؤْمِنِينَ أَعِزَّةٍ عَلَى الْكَافِرِينَ يُجَاهِدُونَ فِي سَبِيلِ اللَّهِ وَلَا يَخَافُونَ لَوْمَةَ لَائِمٍ ۚ ذَٰلِكَ فَضْلُ اللَّهِ يُؤْتِيهِ مَن يَشَاءُ ۚ وَاللَّهُ وَاسِعٌ عَلِيمٌ

O you who have believed, whoever of you should revert from his religion - Allah will bring forth [in place of them] a people He will love and who will love Him [who are] humble toward the believers, powerful against the disbelievers; they strive in the cause of Allah and do not fear the blame of a critic. That is the favor of Allah; He bestows it upon whom He wills. And Allah is all-Encompassing and Knowing.

إِنَّمَا وَلِيُّكُمُ اللَّهُ وَرَسُولُهُ وَالَّذِينَ آمَنُوا الَّذِينَ يُقِيمُونَ الصَّلَاةَ وَيُؤْتُونَ الزَّكَاةَ وَهُمْ رَاكِعُونَ

Your ally is none but Allah and [therefore] His Messenger and those who have believed - those who establish prayer and give zakah, and they bow [in worship].

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا الَّذِينَ اتَّخَذُوا دِينَكُمْ هُزُوًا وَلَعِبًا مِّنَ الَّذِينَ أُوتُوا الْكِتَابَ مِن قَبْلِكُمْ وَالْكُفَّارَ أَوْلِيَاءَ ۚ وَاتَّقُوا اللَّهَ إِن كُنتُم مُّؤْمِنِينَ

O you who have believed, take not those who have taken your religion in ridicule and amusement among the ones who were given the Scripture before you nor the disbelievers as allies. And fear Allah, if you should [truly] be believers.

وَإِذَا نَادَيْتُمْ إِلَى الصَّلَاةِ اتَّخَذُوهَا هُزُوًا وَلَعِبًا ۚ ذَٰلِكَ بِأَنَّهُمْ قَوْمٌ لَّا يَعْقِلُونَ

And when you call to prayer, they take it in ridicule and amusement. That is because they are a people who do not use reason.

قُلْ يَا أَهْلَ الْكِتَابِ هَلْ تَنقِمُونَ مِنَّا إِلَّا أَنْ آمَنَّا بِاللَّهِ وَمَا أُنزِلَ إِلَيْنَا وَمَا أُنزِلَ مِن قَبْلُ وَأَنَّ أَكْثَرَكُمْ فَاسِقُونَ

Say, "O People of the Scripture, do you resent us except [for the fact] that we have believed in Allah and what was revealed to us and what was revealed before and because most of you are defiantly disobedient?"
