as per the command of Almighty God, the Holy Prophet migrated to Medina at the age of fifty three (53) years. This epoch-making night which marked a turning point in the message of Islam, also marks the start of the Muslim Lunar Calendar (Hijra).
The events of history give out a clear verdict that the series of the sufferings, the miseries and the calamities inflicted on the Ahlul Bayt, which culminated at one stage in the wholesale massacre of the Holy Imam Hussain and his faithful devotees at Karbala, and the misfortunes and the assassinations of the other Imams and their families and their devotees, which thereafter followed up to the eleventh Imam Hasan Al-Askari, was inaugurated at the Saqeefa. Had the people remembered the repeated declarations about Imam Ali, and his Ahlul Bayt, the world would never have witnessed the hideous scenes of the sufferings and the massacre of the Holy ones; on the other hand, today the world would have been ruled by the men of God, and humanity had enjoyed the Godly kingdom one arth, and the human race by this time would have been united under one single brotherhood whichwas inaugurated by the Holy Prophet at Madina.
