Al-Akhnas bin Khalifah al-Dabbi states that Ka'b al-Ahbar saw Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) giving legal rulings to the people and asked: Who is this? The people told him: This is Abdullah bin Amr bin al-As. So Ka'b sent one of his companions to him and said: Go and tell him: O Abdullah bin Amr! Do not invent a lie against Allah, or He will destroy you with a punishment, for "he who invents (a lie) has certainly failed" [Surah Ta-Ha: 61] . The man came to him and said the same thing, and Ibn Amr (may Allah be pleased with them both) said: Ka'b has spoken the truth; he who invents a lie has indeed failed. And he did not become angry at all (on hearing this). Then Ka'b sent the same man to him again and said: Ask him what the Gathering (al-Hashr) is, where the souls of the Muslims gather, and where the souls of the idolaters gather. The man came and asked him, and Ibn Amr (may Allah be pleased with them both) said: As for the souls of the Muslims, they gather at Ariha (Jericho); the souls of the idolaters gather at San'a; and as for the beginning of the Gathering, it is a fire that will drive the people along; they will see it at night and will not see it by day. Ka'b's messenger went back and informed him, and Ka'b said: He has spoken the truth. He is a great scholar, so ask him your questions.
