It is narrated from Hazrat Abu Ayyub (may Allah be pleased with him) that I heard the Noble Prophet (peace and blessings be upon him) say: Soon cities will be conquered for you and your armies will be assembled, but some among you will not be willing to go with the army without wages. Indeed, it will happen that a man will leave his people and run away, and present himself before other tribes, saying: Is there anyone who will pay me such-and-such amount so that I may join the battlefield on his behalf? Remember! Such a person will remain a laborer until the last drop of his blood.
