The Holy Prophet (s.a.w.a.) informed: Allah gave me five virtues and five miracles to Ali. He gave me comprehensive words and granted comprehensive knowledge to Ali. He gave me prophethood and made Ali my successor. Allah granted me Kauthar and gave Salsabeel to Ali. He sent revelation to me and gave inspiration to Ali. Allah raised me to Himself (in Meraaj) and He opened the veils of the doors of sky for Ali, whereby whatever I saw in the skies was seen by Ali from the earth.
