Quran 57:8 Al-Hadid, ayah 8 of 29

وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَـٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ ۝٨

57:8 What aileth you that ye believe not in Allah, when the messenger calleth you to believe in your Lord, and He hath already made a covenant with you, if ye are believers?
