﴿ أَوَلَمْ يَرَوْا۟ أَنَّا نَأْتِى ٱلْأَرْضَ نَنقُصُهَا مِنْ أَطْرَافِهَا ۚ وَٱللَّهُ يَحْكُمُ لَا مُعَقِّبَ لِحُكْمِهِۦ ۚ وَهُوَ سَرِيعُ ٱلْحِسَابِ ﴾

“Have, then, they [who deny the truth] never yet seen how We visit the earth [with Our punishment], gradually depriving it of all that is best thereon? For, [when] God judges, there is no power that could repel His judgment: and swift in reckoning is He!”

(See they not) i.e. the people of Mecca (how We visit the land) how We seize the land, (reducing it of) opening it up to Muhammad (pbuh) from (its outlying parts?) from its surrounding sides; it is also said that this refers to the death of the men of knowledge. ((When) Allah doometh) when He decrees the conquest of cities or the death of scholars (there is none that can postpone) there is nothing that can change this. (His doom, and He is swift at reckoning) His torment is severe; it is also said that this means: when He takes people to task, His reckoning is severe.
