14th Ayah from Surah Hud
Sahih International
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?
Abdul Haleem
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?
Mohsin Khan/Hilali
If then they answer you not, know then that the Revelation (this Quran) is sent down with the Knowledge of Allah and that La ilaha illa Huwa: (none has the right to be worshipped but He)! Will you then be Muslims (those who submit to Islam)?
Taqi Usmani
So, if they do not respond to your call, then be assured that it has been sent down with the knowledge of Allah and that there is no god but He. So, do you submit?
Pickthall
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?
Pickthall
"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)?"
