A translation of the text 'al-usul min Ilm al-usul'
The Prophet (PBUH) said: “If Allah intends good for anybody then he
gives him understanding (fiqh) in deen”.
It is not possible for the one with understanding (fiqh) to be without
usul al-fiqh or for the usuli (the one who knows usul al-fiqh) to do
without fiqh if he wants to have understanding (of the deen). - Shaykh
Al-Uthaymin, Kitab Al-Ilm
