Those firmly rooted in knowledge

Those firmly rooted in knowledge (Arabic: الراسخون في العلم) is a recurring theme in the Qur'an and Sunnah.

This verse is a crux interpretum, in that it can be read in two ways, with a pause and without.

[1][2] All those who speak truth, their hearts are firm in belief, do not commit any unlawful acts, those who are well grounded in their knowledge of Deen, their knowledge translates into their actions, does not swear or take false oaths, does not consume wealth unlawfully.

Sunni view that those firmly rooted in knowledge are the body of Muslim Jurists (Arabic: Ulema) who interpret the Divine Law (Arabic: sharia), deriving the Islamic Jurisprudence (Arabic: Fiqh).

This connects to the Arabic for knowledge, ilm, the last word of this term: "al-rasikhuna fi 'l-'ilm" Shi'a view those firmly rooted in knowledge to be Muhammad's household and (Arabic: Ahl al-Bayt) himself.
