Surah Al-Hadid 57:8 — سُورَةُ الحَدِيدِ

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

Surah Al-Hadid (The Iron), ayah 8 of 29. Recited by Muhammad Jibreel (محمد جبريل).
