وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَـٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ
Why should you not have faith in Allah when the Apostle invites you to have faith in your Lord, and He has certainly made a covenant with you, if you are [genuinely] faithful?
