The verse to say at the time of “the appearance of fearful and natural events”
On the appearance of fearful natural events call ye to mind
the might and majesty of your Lord, He Who heareth and seeth all, and say
“Dominion is God’s, the Lord of the seen and the unseen, the Lord of creation”.
(Baha’u’llah, ‘The Kitab-i-Aqdas’)
