Aathaar of the Salaf on Knowledge

Fudayl ibn Ayyad: As for hadeeth, it is better that a man does not hear it than that he hears it and does not act upon it

Abdullah ibn Mas'ood: Learn, so when you have learnt , then act

Maalik ibn Dinar: When a servant seeks knowledge for practise, his knowledge humbles him and when he seeks it for other than that it increases him in immorality and pride by it.

Abu Darda: I am not afraid that it will be said to me: "Oh Aamir what have you learned?", but I am more concerned that it will be said to me: "Oh Aamir, what have you done with what you have learned!"

Ash-Sha'bee: Indeed we are not the scholars but we have heard hadeeth so we have reported them. For the scholars are those who when they know, they act.

Abu Hurairah: The example of knowledge which is not acted upon is like wealth from which nothing is spent in the way of Allaah Azzawajal.

RadhiAllaahu 'anhum ajma'een!
