Surat Fuşşilat - سورة فصلت

إِذْ جَاءَتْهُمُ الرُّسُلُ مِن بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ أَلَّا تَعْبُدُوا إِلَّا اللَّهَ ۖ قَالُوا لَوْ شَاءَ رَبُّنَا لَأَنزَلَ مَلَائِكَةً فَإِنَّا بِمَا أُرْسِلْتُم بِهِ كَافِرُونَ

Muhsin Khan: When the Messengers came to them, from before them and behind them (saying): "Worship none but Allah" They said: "If our Lord had so willed, He would surely have sent down the angels. So indeed! We disbelieve in that with which you have been sent."
