72:19
وَأَنَّهُۥ لَمَّا قَامَ عَبْدُ ٱللَّهِ يَدْعُوهُ كَادُوا۟ يَكُونُونَ عَلَيْهِ لِبَدًا
wa-annahu lammā qāma ʿabdu l-lahi yadʿūhu kādū yakūnūna ʿalayhi libadan
yet when God’s Servant stood up to pray to Him, they pressed in on him.
And when the slave of Allâh (Muhammad صلى الله عليه وسلم) stood up invoking Him (his Lord - Allâh) in prayer they (the jinn) just made round him a dense crowd as if sticking one over the other (in order to listen to the Prophet’s recitation).
