Seeking Knowledge

When a servant seeks knowledge for practice, his knowledge humbles him and when he seeks it for other than that, it increases him in immorality and pride by it. 

- Maalik ibn Dinar

As for hadeeth, it is better that a man does not hear it than that he hears it and does not act upon it. 

- Fudayl ibn Ayyad

Whoever does not consider speech to be part of his action will sin abundantly and whoever acts without knowledge will do more harm than good. 

- Umar ibn 'Abdul-'Aziz
