Anas ibn Malik said, "The Messenger of Allah, may Allah bless
him and grant him peace, said, 'People will continue to ask about things
that do not exist to such an extent that they will say, "Allah created
everything, so who created Allah?"'"
Shahr ibn Hawshab said, "Me and my maternal aunt visited 'A'isha
and said, 'Sometimes something occurs to one of us such that, if he had
spoken about it, that would have been the end of his hopes for the Next
World. If it were to be revealed, he would be killed for it.' She said
the takbir three times and then said, 'The Messenger of Allah, may Allah
bless him and grant him peace, was asked about that and said, "If that
happens to one of you, he should say the takbir three times. Only a believer
feels that.'"
Abu Hurayra reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "Beware of suspicion. Suspicion is the worst type of lie. Do not spy. Do not fight one another. Do not try
to ensnare one another (in sales). Do not envy each other. Do not hate one another. Be slaves of
Allah and brothers."
Abu Hurayra related, "Some people said, 'Messenger of Allah, we
feel in ourselves something which we do not want to speak about and we
have been in that state since sunrise.' He said, 'Have you really felt
like that?' 'Yes,' they said. He said, 'That is clear belief.'"
