Muhammad… as the end of His mission drew nigh, spoke these
words: “Verily, I leave amongst you My twin weighty testimonies: The Book of
God and My Family.” Although many traditions had been revealed by that Source
of Prophethood and Mine of divine Guidance, yet He mentioned only that Book,
thereby appointing it as the mightiest instrument and surest testimony for the
seekers; a guide for the people until the Day of Resurrection.
- Baha’u’llah (‘The Kitab-i-Iqan’)
