Imam Abu Ishaq as-Shatibi al-Andalusi {May Allah have mercy upon him} said:
“Many of the ignorant think that the Sufis are lax in conforming to the law. Far be it from them to be attributed such a belief! The very first foundation of their path is the Sunnah and the avoidance of what contravenes it!”
{Kitab al-I’tisam}
