فَإِن لَّمْ يَسْتَجِيبُواْ لَكُمْ فَاعْلَمُواْ أَنَّمَا أُنزِلِ بِعِلْمِ اللّهِ وَأَن لاَّ إِلَـهَ إِلاَّ هُوَ فَهَلْ أَنتُم مُّسْلِمُونَ
[11:14]
But if they do not answer you, then know that it is revealed by Allah's knowledge and that there is no god but He; will you then submit?
"If then they (your false gods) answer not your (call), know ye that this revelation is sent down (replete) with the knowledge of Allah, and that there is no god but He! will ye even then submit (to Islam)?"
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?
