It was
narrated that Anas bin Malik said:
“A funeral (procession)
passed
by the Prophet (ﷺ) and they praised (the deceased) and spoke
well
of him. He said: ‘(Paradise is) guaranteed for him.’ Then another
funeral passed by and they spoke badly of him, and he (the Prophet
(ﷺ)) said: ‘(Hell is) guaranteed for him.’ It was said: ‘O
Messenger
of Allah, you said that (Paradise was) guaranteed for this
one and
that (Hell was) guaranteed for the other one.’ He said: ‘It
is the
testimony of the people, and the believers are the witnesses
of Allah
on earth.’”
