Hazrat Ibn Abbas (may Allah be pleased with them) narrates that I asked Hazrat Ka'b, "What is Sidrat al-Muntaha?" Hazrat Ka'b replied: "It is a tree where the knowledge of the angels ends; there they receive Allah's command, and their knowledge does not go beyond that point." I asked him about Jannat al-Ma'wa. Hazrat Ka'b replied: "It is a paradise in which there are green birds, and the souls of the martyrs go there."
