۞ وَيَسۡتَنۢبِـُٔونَكَ أَحَقٌّ هُوَۖ قُلۡ إِي وَرَبِّيٓ إِنَّهُۥ لَحَقّٞۖ وَمَآ أَنتُم بِمُعۡجِزِينَ ٥٣
English translation (Saheeh International)
And they ask information of you, [O Muḥammad], "Is it true?" Say, "Yes, by my Lord. Indeed, it is truth; and you will not cause failure [to Allāh]."
Brief commentary
The idolaters ask you O Messenger f this punishment which they have been promised is true? Tell them: 'By Allah! It is the very truth and you cannot get away from it.'
