Masudi, the great historian, writes: "If the glorious name of being among the first Muslims, a comrade of the Prophet in exile, his faithful companion in the struggle for the faith, his intimate friend in life and his kinsman, if a true knowledge of his teachings and of the Book, if self abnegation and practice of justice, if honesty, purity and love of truth, if a knowledge of law and science constitutes a claim to pre-eminence then all must regard Ali as one of the foremost Muslims."
