It is narrated from Hazrat Safina (may Allah be pleased with him) that I heard the Noble Prophet (peace and blessings be upon him) say: "The caliphate will remain for thirty years, after that kingship will come." Hazrat Safina (may Allah be pleased with him) counted it as follows: two years of the caliphate of Hazrat Siddiq Akbar (may Allah be pleased with him), ten years of Hazrat Umar Farooq (may Allah be pleased with him), twelve years of Hazrat Usman Ghani (may Allah be pleased with him), and six years of Hazrat Ali Murtaza (may Allah be pleased with him) (making a total of thirty years).
