Narrated by 'Abdullah bin Mas'ud

The Prophet 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."
