Al-Hujurat 49:18

إِنَّمَا الْمُؤْمِنُونَ الَّذِينَ آمَنُوا بِاللَّهِ وَرَسُولِهِ ثُمَّ لَمْ يَرْتَابُوا وَجَاهَدُوا بِأَمْوَالِهِمْ وَأَنفُسِهِمْ فِي سَبِيلِ اللَّهِ ۚ أُولَـٰئِكَ هُمُ الصَّادِقُونَ

The believers are only the ones who have believed in Allah and His Messenger and then doubt not but strive with their properties and their lives in the cause of Allah. It is those who are the truthful.

قُلْ أَتُعَلِّمُونَ اللَّهَ بِدِينِكُمْ وَاللَّهُ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ ۚ وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيمٌ

Say, "Would you acquaint Allah with your religion while Allah knows whatever is in the heavens and whatever is on the earth, and Allah is Knowing of all things?"

يَمُنُّونَ عَلَيْكَ أَنْ أَسْلَمُوا ۖ قُل لَّا تَمُنُّوا عَلَيَّ إِسْلَامَكُم ۖ بَلِ اللَّهُ يَمُنُّ عَلَيْكُمْ أَنْ هَدَاكُمْ لِلْإِيمَانِ إِن كُنتُمْ صَادِقِينَ

They consider it a favor to you that they have accepted Islam. Say, "Do not consider your Islam a favor to me. Rather, Allah has conferred favor upon you that He has guided you to the faith, if you should be truthful."
