It is narrated from Sayyiduna Zuhair Thaqafi (may Allah be pleased with him), he says: I heard the Noble Prophet (peace and blessings be upon him) saying at the place of Nabawah in Ta’if: O people! Surely, the time is near when you will recognize the people of Paradise and the people of Hell, or the righteous and the wicked. A man said: O Messenger of Allah! How is that? You (peace and blessings be upon him) said: Through bad and good praise; in reality, you are Allah’s witnesses over one another in giving testimony.
