Al Hadid Ayah 8

وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ‌ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُواْ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَـٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ ٨ Why do you not believe in Allah while the Messenger is inviting you to have faith in your Lord, although He has already taken your covenant, if you will ever believe.
