It was
narrated from Fatimah bint Husain that her father said:
The
Prophet
(ﷺ) said: “Whoever was stricken with a calamity and when he
remembers it he says ‘Inna lillahi, wa inna ilayhi raji’un
(Truly, to
Allah we belong and truly, to Him we shall return),’
even though it
happened a long time ago, Allah will record for him a
reward like that
of the day it befell him.”
