Abu Sa’eed Al-Khudri said:
“The Messenger of Allah (ﷺ) stood up
and
addressed the people saying: ‘No, by Allah, I do not fear for
you, O
people, but I fear the attractions of this world that Allah
brings
forth for you.’ A man said to him: ‘O Messenger of
Allah(ﷺ), does
good bring forth evil?’ The Messenger of Allah
(ﷺ) remained silent
for a while, then he said: ‘What did you
say?’ He said: ‘I said, does
good bring forth evil?’ The
Messenger of Allah (ﷺ) said: ‘Good does
not bring forth anything
but good, but is it really good? Everything
that grows on the banks
of a stream may either kill if overeaten or
(at least) make the
animals sick, except if an animal eats its fill of
Khadir* and then
faces the sun, and then defecates and urinates,
chews the cud and
then returns to graze again. Whoever takes wealth in
a lawful manner,
it will be blessed for him, but whoever takes it in
an unlawful
manner, his likeness is that of one who eats and it never
satisfied.’”
