“The Messenger of Allah (ﷺ) addressed us in Nabawah” or
Banawah – he (one of the narrators) said: “Nabawah is near Ta’if”
–
“And said: ‘Soon you will be able to tell the people of
Paradise from
the people of Hell.’ They said: ‘How O Messenger of
Allah?’ He said:
‘By praise and condemnation. You are Allah’s
witnesses over one
another.’”
Sunan Ibn Majah Book 37, Hadith 122
