Qur'an 57:8

وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَـٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ

“And why do you not believe in Allāh while the Messenger invites you to believe in your Lord and He has taken your covenant, if you should [truly] be believers?”
