Sayyiduna Usama bin Zaid (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) said to his companions: Is there anyone preparing for Paradise? For Paradise is a thing for which there is no example. By the Lord of the Ka'bah, it is a light that is glittering. It is a flower that is waving. It is a palace that is well-connected. It is a river that is continuously flowing. There are fruits there, abundant and ripe, and wives who are beautiful and very fine garments. It is a place where one will reside forever. That place is lush, green, elevated, superior, safe and sound. The people said: O Messenger of Allah! We are prepared for it. The Prophet Muhammad (peace and blessings be upon him) said: Say, "In sha Allah" (If Allah wills). Then the Prophet Muhammad (peace and blessings be upon him) mentioned Jihad and encouraged it.
