﴿ وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ ﴾

“And why should you not believe in God, seeing that the Apostle calls you to believe in [Him who is] your Sustainer, and [seeing that] He has taken a pledge from you? [Why should you not believe in Him] if you are able to believe [in anything]?”

(What aileth you) O people of Mecca (that ye believe not in Allah) that you deny Allah's divine Oneness, (when the messenger) Muhammad (pbuh) (calls you to believe in your Lord) to profess your Lord's divine Oneness, (and He hath already made a covenant with you) and He has already taken your declaration of Allah's divine Oneness, (if ye are believers) on the Day of Covenant?
