Abu Hurayrah (radiyAllaahu anhu) reports that,
The Messenger of Allaah (sallAllaahu alayhi wa sallam) said, "faith
has sixty or seventy odd branches. The least of them is to remove
something harmful from the road and the most lofty of them is the
saying, ‘none has the right to be worshipped save Allaah,’ and modesty
is a branch of faith."
