In the Name of Allah, the Extremely Merciful, the Bestower of Mercy
Shaykh Saalih al-Fawzaan, may Allah preserve him, said:
Beneficial knowledge is not ample speech or treatises. No, rather [beneficial] knowledge depends on the usool upon which it is built, though it may be little.
Translated by Umm Sufyaan Faatimah
 Shaykh Saalih al-Fawzaan, Sharh Thalathatul-Usool tape no. 1, 0:15:24-0:15:37.
