Muslims doctrines are not only based by the Holy Qur'an But
also the Hadeeths, or the sayings of the Prophet Muhammad.
Mister, please Muslims are not brainwashed... Its not Louis
Armstrong, he was Neil Armstrong. And you are right, he did not
convert. But you know rumors/myths are
inevitable.
About Pigs and Dogs
The proof of this is the Hadeeth of the Prophet SallAllahu 'alahi
wa-sallam where he said:
"If a dog licks in the utensils of one of you, then he should wash
it seven times, one of them with sand."
The Hanbalis included the najaasah of pig in the same ruling by way
of Qiyas (analogical deduction) over a dog. In our time, sand has
been replaced with soap and detergent etc, and surely they are
better at cleaning then sand, and Allah knows best. An important
point to note and remember is that Ghasl or washing means for water
to run over a surface, whereas al-Mash or wiping means for one to
wipe his wet hand over a surface.
P.S I am sure everyone knows that pork is forbidden for consumption
thus i wont post the explanation for that.
As for hair dyeing:
Pure black dye is not permissible. Rasulullah "There will be people
who will come later (in my Ummah) and apply black dye. They will
not even smell the fragrance of paradise." (Abu Dawood). However,
it is permissible for a Mujaahid (warrior) to apply black dye in
order to give the impression of being young. (Jawahirul Fiqh vol 2
pg. 421)
What is the ruling on dying hair?
The ruling on dying hair differs for men and women. For men, it is
forbidden except for two occassions, which are:
1) Ones hair has turned grey at a young age in which case it is
permissible to dye it to its original colour, i.e, black.
2) Ones hair has turned grey due to old age in which case it is
permissible to dye it other than the colour black.
3) When one is in war in which case it is permissible to dye ones
hair black to deceive the enemy.
As for women, they are permitted to dye their hair with any colour
at any time if the following conditions are observed:
1) The hair colour used is within the natural colours of hair that
has been created by Allah s.w.t such as brown, blonde, black and
auburn.
2) The hair must not be exposed to men who are not mahram.
3) If she is married, initial permission from the husband must be
obtained first.
To dye the hair any other color besides black e.g. Mehndi or Katm
(type of grass) is permissible. This was the practice of Rasulullah
and the Sahaba, Radi-Allahu anhum. (Jawahirul Fiqh vol 2 pg
421).
The general conditions for dying hair are that the product used
must not contain any najis and it must not be waterproof. This is
to ensure that water from wudhu and ghusl reaches the hair
sufficiently. Products that have the Halal sign on it do not
contain any najis but they may be waterproof.
Mister, i am not being old-fashioned here. Im just
following the laws. Please refer to your nearest local Islamic
Center/Mosque, theres no use getting information from a Non-Muslim
or those with no proper education.
About the Alcohol, i
know, you cant consume it but you do can use it for whatever other
reasons. It has to be synthetic though. The naturally-made Alcohol
is a total haraam. FYI, synthetic meaning, the Alcohol is made
chemically.
In all, Muslims, can dye their hair with permitted hair dyes like
henna that is not waterproof. And he/she must avoid the color of
his/her natural color. Like if i am a blond, i am forbidden from
dying my hair yellow except for if my hair greys too early. This is
to avoid the person from forgetting that we are all getting old. It
serves like a reminder.
