ٱلْجِنّ : ١٩

  • وَأَنَّهُۥ And that
  • لَمَّا when
  • قَامَ stood up
  • عَبۡدُ (the) slave
  • ٱللَّهِ (of) Allah
  • يَدۡعُوهُ calling (upon) Him
  • كَادُواْ they almost
  • يَكُونُونَ became
  • عَلَيۡهِ around him
  • لِبَدٗا a compacted mass
And that when the Servant [i.e., Prophet] of Allāh stood up supplicating Him, they almost became about him a compacted mass."1
