Muhammad on Ja'far al-Sadiq

“Everything has a foundation, and the foundation of Islām is our affection for the household of our Prophet.”

“The person who is aware of the present situations of his time, will never get involved with falsifying and wrongdoing.”

“There are two kinds of scholars: those who act on their knowledge, these are the saved ones; and those who do not put into practise what they know, these are led to their downfall.”

“Seek Knowledge and adorn it with forbearance and dignity. Be humble to those whom you teach and to those from whom you learn. Don't be tyrannical in your teaching conduct, for you will forfeit that to which you are entitled to (the reward) on account of it.”

“My words are the words of my father, and the words of my father are the words of my grandfather, and the words of my grandfather are the words of my great-grandfathers - Hasan and Husayn; and their words are the words of Ali, and the words of Ali are the words of the Prophet of Allah; and the words of the Prophet are the words of Allah.”

“One who does not use his intelligence will not succeed and one who does not use his knowledge will have no intellect. One who understands will attain nobility and excellence, and one who is tolerant will triumph. Knowledge is a shield (against evil), truth begets honour and ignorance disgrace, understanding is distinction, generosity is salvation and good manners command love and respect.”
