Jabir bin Abdullah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) said: "Do not consider your provision to be slow in coming, for a servant does not die until the last of the provision that is his has reached him. Fear Allah, seek provision in a good manner through lawful means, and leave the unlawful."
