Narrated 'Abdullah bin Mas'ud:
The Prophet (sallallahu alayhi wa salam) said, "Do not wish to be like
anyone except in two cases. (The first is) A person, whom Allah has
given wealth and he spends it righteously; (the second is) the one
whom Allah has given wisdom (the Holy Qur'an) and he acts according to
it and teaches it to others."
