One who acts without knowledge is like one who travels off the path

Bismillahir Rahmanir Rahim

In the name of Allah, the Most Beneficent, the Most Merciful

It is reported that Al-Hasan Al-Basrî – Allâh have mercy on him – said:
One who acts without knowledge is like one who travels off the path; and the one who acts without knowledge corrupts more than he rectifies. So seek knowledge in a way that does not harm your worship, and seek to worship [Allâh] in a way that does not harm [your seeking of] knowledge. For verily, there were people (the Khawârij extremists) who sought to worship [Allâh] but abandoned knowledge until they attacked the Ummah of Muhammad – Allâh’s praise and peace be upon him – with their swords. But if they had sought knowledge, it would not have directed them to do what they did.
Quoted by Ibn ‘Abd Al-Barr, Jâmi’ Bayân Al-’Ilm wa Fadlihi article 905.

  Has not the time yet come for those who believe that 

their hearts should be humble for the remembrance of Allah 

and what has come down of the truth?
