﴿ وَلَئِنْ أَخَّرْنَا عَنْهُمُ ٱلْعَذَابَ إِلَىٰٓ أُمَّةٍۢ مَّعْدُودَةٍۢ لَّيَقُولُنَّ مَا يَحْبِسُهُۥٓ ۗ أَلَا يَوْمَ يَأْتِيهِمْ لَيْسَ مَصْرُوفًا عَنْهُمْ وَحَاقَ بِهِم مَّا كَانُوا۟ بِهِۦ يَسْتَهْزِءُونَ ﴾

“And thus it is: if We defer their suffering until a time-limit set [by Us], they are sure to say, "What is preventing it [from coming now]?" Oh, verily, on the Day when it befalls them there will be nothing to avert it from them; and they shall be overwhelmed by the very thing which they were wont to deride.”

(And if We delay for them the doom until a reckoned time) until an appointed time: the Day of Badr, (they will surely say) i.e. the people of Mecca: (What withholdeth it) from us tomorrow, out of mockery? (Verily on the day when it) the chastisement (cometh unto them, it cannot be averted from them) the chastisement will not be averted from them, (and that which they derided) the chastisement for their derision of Muhammad (pbuh) and the Qur'an (will surround them) it will descend upon them and it is enjoined on them.
