The Starting Point of All Deviation

Shaikh Rabīʿ ibn Hādī Al-Madkhalī, may Allāh protect him, said:

A Muslim is required to be from the group [of people who support the religion] of Allāh, obeying Allāh, being submissive to Allāh. It’s upon him to have al-ḥayāʾ [restraining oneself from unseemly things out of a sense of shame or shyness] before Allāh, Exalted is He and All-High. All deviations find their start in weakness of al-ḥayāʾ, as he ﷺ said: “If you don’t hold yourself back from unseemly things out of a sense of shame [before Allāh], then do as you will.”¹
