Narated By 'Abdullah RA: Allah's Apostle PBUH said, "Do not wish to be like anyone, except in two cases: (1) A man whom Allah has given wealth and he spends it righteously. (2) A man whom Allah has given wisdom (knowledge of the Quran and the Hadith) and he acts according to it and teaches it to others."
