Whoever does not pronounce the two testimonies is a disbeliever; whoever abandons the prayer is a disbeliever; whoever withholds the zakah is a sinner; whoever neglects the ḥajj is a sinner; and whoever does not fast is a sinner. Allah is the One who grants success.

When they do so, their blood and property are protected from me—except by the right of Islam—and their reckoning rests with Allah.” Agreed upon.
