(Al Hadeed) 57 : 8
وَمَا لَكُمْ لَا تُؤْمِنُونَ بِاللَّهِ ۙ وَالرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَاقَكُمْ إِنْ كُنْتُمْ مُؤْمِنِينَ
What is to you for not to believe with Allah, while Messenger is calling you to believe with your Lord? And surely He has taken from you the covenant, if you are believers.
See explanation 3: 81-82, 193; 5: 57; and 48: 10.
