O' people what I fear most about you are two things - acting according to desires and extending of hopes. As regards acting according to desires, this prevents from truth; and as regards extending of hopes, it makes one forget the next world. You should know this world is moving rapidly and nothing has remained out of it except last particles like the dregs of a vessel which has been emptied by someone. Beware, the next world is advancing, and either of them has sons i.e. followers.
