Imâm Mâlik ibn Anas, one of the most eminent scholars of the second century after the Hijrah,
delivered the following aphorism on the relationship between Islamic law and Sufism (tasawwuf):
man tafaqqaha wa-lam yatasawwafa fa-qad tafassaq
'He who learns jurisprudence and neglects Sufism becomes a reprobate;'
wa-man tasawwafa wa-lam yatafaqqaha fa-qad tazandaq
'he who learns Sufism and neglects jurisprudence becomes an apostate;'
wa-man jama`a baynahumâ fa-qad tahaqqaq
'and he who combines both attains the realization of the Truth.'
To which I have appended my own corollary:
wa-man taraka kilayhimâ fa-qad tahammaq
'...and he who neglects both falls into imbecility.'
