In Sermon 239, page 357, Ali describes the status of Ahlul Bayt:
They [Ahlul Bayt] are the life for [Divine] knowledge and the death keel to ignorance.
▪ Their forbearance tells you of their knowledge, and their behavior about their integrity
▪ Their silence tells you of their wisdom.
▪ Never do they deviate from Truth, nor [among themselves] will they differ about it.
▪ Ahlul Bayt are the pillars in support of Islam. They are the haven to take protection in.
▪ With them the Right has returned to its proper place, and because of them Falsehood has retreated from its place and its tongue rooted out.
▪ Ahlul Bayt understood the correct spirit of Islam, attentively and painstakingly.
▪ They carried Islam's precepts into practice. And all this was not by heresy or from narrators.
▪ Lo! The narrators of knowledge are many but those who truly understand it are only few.
