Abdullah ibne-Umar (Radiyallahu Anhuma) narrates
that Rasulullah (Sallallahu Alaihi Wasallam) said:
"Envy is justified in regard to two types of persons only:
a man whom Allah Subhanahu wa ta'ala
has given knowledge of the Qur'an,
and so he recites it
during the night and during the day;
and a man whom Allah Subhanahu wa ta'ala
has given wealth
and so he spends ( to please Allah ) from it
during the night and during the day.''
{ Muslim }
