1st Dhu al-Hijjah; Anniversary of Heavenly Marriage of Imam Ali with Sayyida Fatimah Al-Zahra

Lady Umm-e-Salma narrates that: One day Imam Ali (AS) approached the Prophet Mohammad (P.B.U.H) at his house. Imam Ali (AS) entered and greeted the Prophet (P.B.U.H) and the Prophet (P.B.U.H) replied in the same kind manner. Imam Ali (AS) sat down and he was so much shy that he continued staring at the ground and could not utter a word.
