It was narrated from Abu Bakr bin Abu Zuhair Ath-Thaqafi, that his father said:“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.’”
