Praise be to Allaah.
Firstly:
it is haraam to shave the beard; it is obligatory (waajib) to leave it to
grow.
Secondly:
it is not permissible to salute the flag.
Thirdly:
it is obligatory (waajib) to govern by the sharee’ah of Islam, and to
refer to it for judgement. It is not permissible for a Muslim to greet
colleagues or superiors with the greeting of the foreigners, because of
the reports which state that it is forbidden to imitate them and because
this represents exaggerated respect for them.
Fourthly:
Whoever fights to make the word of Allaah supreme and to protect the
Muslims and their lands from the enemy, is fighting for the sake of
Allaah, and if he is killed he is a shaheed (martyr). What counts is the
aim and intention. You can have an intention which is different from the
intention of the army, such as intending to make the word of Allaah
supreme in your jihaad (so long as it is permissible, according to
sharee’ah, to fight the group against whom you are fighting), even if
others have different intentions, such as fighting for their country.
Fifthly:
it is obligatory (waajib) to obey your parents so long as this does not
entail disobeying Allaah, because there should be no obedience to any
created being if it involves disobedience of the Creator.
And
Allaah is the source of strength. May Allaah bless our Prophet Muhammad
and his family and companions, and grant them peace.
