"Glory be to Allah, the King, the Holy. Glory be to Allah, the Great, the Most High. There is no god except Allah, the Living and Self­ Subsisting. "

Whenever the Angel would say this tasbih, all the peacocks that are on the Earth would start to praise Allah (SWT) and open their wings up in respect (of Allah ).

Whenever this Angel in the heaven would become quiet, the peacocks on the Earth would become quiet. The Angel in the heaven had green hair and white wings ‑ so white that no one has ever seen anything that white before. Under its green hair, there are white wings which are very beautiful ‑ the green which until now has never been seen before."
