"Do not wish to be like anybody except in two cases: The case of a man whom Allah has given wealth and he spends it in the right way, and that of a man whom Allah has given religious wisdom (i.e., Qur'an and Sunna) and he gives his verdicts according to it and teaches it." (to others i.e., religious knowledge of Qur'an and Sunna (Prophet's Traditions))."
