(Al-Qalam) 68 : 19
فَطَافَ عَلَيْهَا طَائِفٌ مِنْ رَبِّكَ وَهُمْ نَائِمُونَ
Thus a group from your Lord visited upon it while they were sleeping.
A group from your Lord visited upon your garden means Allah sent His angels to that garden and destroyed their cultivation completely. See explanation 67: 16-18.
