“Whenever he
appointed a man to lead a military detachment, the Messenger of Allah
(ﷺ) would advise him especially to fear Allah and treat the Muslims
with him well. He (ﷺ) said: ‘Fight in the Name of Allah and in
the
cause of Allah. Fight those how disbelieve in Allah. Fight but do
not
be treacherous, do not steal from the spoils of war, do not
mutilate
and do not kill children. When you meet your enemy from
among the
polytheists, call them to one of three things. Whichever of
them they
respond to, accept it from them and refrain from fighting
them. Invite
them to accept Islam, and if they respond then accept it
from them and
refrain from fighting them. Then invite them to leave
their land and
move to the land of the polytheists. Tell them that if
they do that,
then they will have the same rights and duties as the
polytheists. If
they refuse, then tell them that they will be like
the Muslim Bedouins
(who live in the desert), subject to the same
rulings of Allah as the
believers. But they will have no share of
Fay’* or war spoils, unless
they fight alongside the Muslims. If
they refuse to enter Islam, then
ask them to pay the Poll-tax. If
they do that, then accept it from
them and refrain from fighting
them. But if they refuse, then seek the
help of Allah against them
and fight them. If you lay siege to them
and they want you to give
them the protection of Allah and your
Prophet, do not give them the
protection of Allah and your Prophet,
rather give them your
protection and the protection of your father and
your Companions, for
if you violate your protection and the protection
of your fathers,
that is easier than violating the protection of Allah
and the
protection of His Messenger. If you lay siege to them and they
want
you to let them come out with a promise of the judgement of Allah
and
His Messenger (ﷺ), do not offer them a promise of the judgement
of
Allah and His Messenger (ﷺ), rather offer them your judgement,
because you do not know if you will actually pass (the same as)
Allah’s judgement regarding them or not.’”
