There is no family in the world so mutually supportive, nor a tribe in such agreement, nor so enlightened a community or society as the family, tribe, community and society of the Prophet’s Family.
Yes, the Prophet’s Family has raised hundreds of sacred heroes, and produced thousands of spiritual leaders of the Umma, and has been nurtured with the leaven of the reality of the Qur’an and the light of belief and honour of Islam, and has thus been perfected. It is therefore totally reasonable that through reviving the Sharia of Muhammad (PBUH) and his Sunna and the reality of the Qur’an at the end of time, and proclaiming them and putting them into practice, they should display to the world the perfect justice and veracity of the Great Mahdi, their Commander-in-Chief. This is also both necessary and essential and demanded by the principles of human society. (The Rays, 111-112)
The extraordinary compassion the Most Noble Prophet (PBUH) showed towards Hasan and Husain in their childhood and the great importance he gave them was not only due to love arising from natural kindness and family feeling, it was rather because they were each the tip of a luminous thread of the function of prophethood, and the source, sample, and index of a community of great consequence which would receive the legacy of prophethood.
