أَوَلَمْ يَرَوْا۟ أَنَّا نَأْتِى ٱلْأَرْضَ نَنقُصُهَا مِنْ أَطْرَافِهَا ۚ وَٱللَّهُ يَحْكُمُ لَا مُعَقِّبَ لِحُكْمِهِۦ ۚ وَهُوَ سَرِيعُ ٱلْحِسَابِ
See they not how we aim to the land, reducing it of its outlying parts? (When) Allah doometh there is none that can postpone His doom, and He is swift at reckoning.

Merits of the Helpers in Madinah (Ansaar)
Chapter: The building of the Ka'bah
Narrated Jabir bin `Abdullah:
When the Ka`ba was rebuilt, the Prophet (ﷺ) and `Abbas went to carry stones. `Abbas said to the Prophet (ﷺ) "(Take off and) put your waist sheet over your neck so that the stones may not hurt you." (But as soon as he took off his waist sheet) he fell unconscious on the ground with both his eyes towards the sky. When he came to his senses, he said, "My waist sheet! My waist sheet!" Then he tied his waist sheet (round his waist).
