The Prophet (sallallahu `alayhi wa sallam) said, “A person is upon the Deen of his friend, so let each of you look to whom you befriend.” [Abu Dawud, 4833]

As-salamu `alaykum wa rahmatullah A chapter I took from one of my
books… very insightful. "… Know that not everyone is suited to be your
friend. The Prophet (sallallahu `alayhi wa sallam) said, "A person is
upon the Deen of his friend, so let each of you look to whom you
befriend." [Abu Dawud, 4833]
