Suhaib Radiyallahu Ďanhu narrates
that Rasullullah Sallallahu Ďalaihi wasallam said:
It is remarkable that everything turns out well for a believer;
and that applies only to a believer.
If happiness befalls him he is thankful
and it turns out well for him,
and if misfortune befalls him,
he shows endurance
and it turns out well for him.
