11:14
فَاِلَّمْ یَسْتَجٖیبُوا لَكُمْ فَاعْلَمُٓوا اَنَّمَٓا اُنْزِلَ بِعِلْمِ اللّٰهِ وَاَنْ لَٓا اِلٰهَ اِلَّا هُوَۚ فَهَلْ اَنْتُمْ مُسْلِمُونَ
Fai llam yastajeeboo lakum faiAAlamoo annama onzila biAAilmi Allahi waan la ilaha illa huwa fahal antum muslimoona
Translations
And if they do not respond to you - then know that the Qur'an was revealed with the knowledge of Allah and that there is no deity except Him. Then, would you [not] be Muslims
Saheeh International
And if they answer not your prayer, then know that it is revealed only in the knowledge of Allah; and that there is no Allah save Him. Will ye then be (of) those who surrender
