SHAFAQNA – The Prophet of Islam (PBUH) said: O’ Ali (AS), I am the city of knowledge and you are its gate, one cannot enter the city except through its gate; you are the leader of my Ummah (Islamic nation) and my successor in this city, the one who obeys you is prosperous and the one who disobeys you is helpless; the one who loves you has benefited and your enemy is in loss [1].
