Surah An-Najm · 53:16

Same source as the post on this event that carries this ayah.

“I stopped at the Sidrat al-Muntaha — it is in the 6th heaven. Everything that is raised up from the earth (e.g., du'a, prayer, good deeds, good words) stops at Sidrat al-Muntaha, and it absorbs them. And from it originates and descends down everything that is coming to this earth (e.g., Allah's rahma, rain). When the Tree was enveloped by what it was enveloped by, there were butterflies made out of gold.”
