Ibn ‘Abbas reported God’s messenger as saying, “Some among
my people will become learned in religion, will recite the Qur’an, and
say that they will go to princes and get some of their worldly goods,
but withdraw from them with their religion. That cannot be; for, as
what is gathered from tragacanth trees consists only of thorns, so what
is gathered from drawing near to them consists only of . . . ” Muhammad
b. as-Sabbah said that he obviously meant “sins." Ibn Majah transmitted it.
