(Qaaf) 50 : 44
يَوْمَ تَشَقَّقُ الْأَرْضُ عَنْهُمْ سِرَاعًا ۚ ذَٰلِكَ حَشْرٌ عَلَيْنَا يَسِيرٌ
The Day the earth will be split ascender, they will come hastily; such a gathering is easy for Us.
On the Last Day, whatever is in the earth will come out just like flies come out from the earth. Thus, everyone will hasten to the assembly of Judgment at Mecca just like flies moving to the point of light. See explanation 14: 43; 99: 2-6; and 101: 4-5.
