The Holy Prophet (s.a.w.a.) – O Ali, surely Allah, the Almighty, has said – You and your Shias and lovers of your Shias and lovers of lovers of your Shias have been forgiven. And gives glad tidings to you that surely you are الْأَنْزَعُ الْبَطِينُ (meaning a man with a receding hairline and a potbelly), you have receded from apostasy and possess a belly filled with knowledge
