Imam Ali (AS) was the First Caliph of the Prophet Muhammad (SAWA). The three rulers who took over the government through Saqeefah were never divine caliphs but they took the government by worldly political means which were never supported by Quran or the Prophet. Saqeefah was planned by few opponents of Ahlul Bayt to snatch away their rights when Ameerul Mo;miners was busy in the funeral of the Prophet (SAWA). Imam Ali (AS) never accepted any of those three rulers who came through Saqeefah.
