Surah Al-Hadid 57:8
وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ ٨
EnglishSahih International
And why do you not believe in Allah while the Messenger invites you to believe in your Lord and He has taken your covenant, if you should [truly] be believers?
