And that when the Servant [i.e., Prophet] of Allāh stood up supplicating Him, they almost became about him a compacted mass."1
Translation: Saheeh International (English)
1 Crowding on top of each other in the manner of locusts in order to hear him (ﷺ). "They" may refer to the jinn or to the disbelievers among the Arabs.
And that when Allah’s servant, Muhammad (peace be on him) stood up to worship His Lord in Batn Nakhla, the jinn were almost piled on top of him because of the huge crowd when they heard him reciting the Qur’ān.
