“I saw the Bedouins
asking
the Prophet (ﷺ): ‘Is there any harm in such and such, is
there
any harm in such and such?’ He said to them: ‘O slaves of Allah!
Allah has only made harm in that which transgresses the honor of
one’s
brother. That is what is sinful.’ They said: ‘O Messenger
of Allah! Is
there any sin if we do not seek treatment?’ He said:
‘Seek treatment,
O slaves of Allah! For Allah does not create any
disease but He also
creates with it the cure, except for old age.’
They said: ‘O Messenger
of Allah, what is the best thing that a
person may be given?’ He said:
‘Good manners.’”
