Required Learning [What is a Muslim Required to Study?]

It is reported that Hasan b. Rabī’ asked ‘Abdullāh b. Al-Mubārak – Allāh have mercy on him – about the meaning of the hadith, “Seeking knowledge is obligatory upon every Muslim”. He replied:

It is not [the expert knowledge of hadith and fiqh] you are seeking. Seeking knowledge is an obligation when a man comes to something concerning his religion (dīn): he is to ask about it until he knows it.
