وَأَنَّهُۥ لَمَّا قَامَ عَبْدُ ٱللَّهِ يَدْعُوهُ كَادُوا۟ يَكُونُونَ عَلَيْهِ لِبَدًا
Wa annahoo lammaa qaama 'adul laahi yad'oohu kaadoo yakoonoona 'alaihi libadaa
Allah'ın kulu Muhammed, O'na yalvarmak, namaz kılmak için kalkınca, nerdeyse, çevresinde keçeleşirler, birbirlerine girerlerdi.
And when the servant of God stood calling upon him, they nearly pressed in on him in throngs.
Libad describes wool or hair pressed into a solid mat, one body with no gaps in it, and the word carries that density into the picture of a crowd. Early readers disagreed about the crowd: the jinn packing in to hear the recitation, which fits the surah around it, or the Meccans massing against him. Standing in prayer is all the servant of God is doing when it happens.
