11:14
فَإِلَّمْ يَسْتَجِيبُوا۟ لَكُمْ فَٱعْلَمُوٓا۟ أَنَّمَآ أُنزِلَ بِعِلْمِ ٱللَّهِ وَأَن لَّآ إِلَـٰهَ إِلَّا هُوَ ۖ فَهَلْ أَنتُم مُّسْلِمُونَ
fa-illam yastajībū lakum fa-iʿ'lamū annamā unzila biʿil'mi l-lahi wa-an lā ilāha illā huwa fahal antum mus'limūna
If they do not answer you, then you will all know that it is sent down containing knowledge from God, and that there is no god but Him. Then will you submit to Him?
If then they answer you not, know then that it [the Revelation (this Qur’ân)] is sent down with the Knowledge of Allâh and that Lâ ilâha illa Huwa: (none has the right to be worshipped but He)! Will you then be Muslims (those who submit in Islâm)?
