Whoever does not act in accordance with his knowledge, then his knowledge has not benefited him; rather it has harmed him.
Whoever does an act which is not in accordance with the Sunnah, then his act is void.
Love of Allaah ‘Azza wa Jall entails love of the Qur.aan, and love of the Messenger ﷺ entails acting in accordance with his Sunnah.
No hadeeth of the Messenger of Allaah ﷺ has ever reached me, except that I have acted according to (practiced) it – even if only once.
Beautify knowledge [by acting in accordance to it], and do not beautify yourself with it.
