The Hair

Tirmidhi Hadith (Hadith 1523)

Allah's Messenger (peace be upon him) was neither tall nor short, he had a large head and beard, the palms of his hands and his feet were calloused, he had a reddish tinge, he had large joints, the hair on his breast was long, and when he walked he bent forward as though he were descending a slope. I have never seen anyone like him before or since.

 * It is permissible for men to shave/trim their chest or stomach hair if required or due to any problem(like itching)

Sahih Al-Bukhari Hadith (Hadith 7.778)

Allah's Apostle said, "To shave the pubic hair, to clip the nails and to cut the mustaches short, are characteristics of the Fitra."

Sunan of Abu-Dawood Hadith (Hadith 1958)

The Apostle of Allah (peace be upon him) said: Do not pluck out grey hair. If any believer grows a grey hair in Islam, he will have light on the Day of Resurrection. (This is Sufyan's version). Yahya's version says: Allah will record on his behalf a good deed for it, and will blot out a sin for it.

Sunan of Abu-Dawood Hadith (Hadith 1931)

The Apostle of Allah (peace be upon him) forbade combing the hair except every second day.

Al-Tirmidhi Hadith (Hadith 1181)

Allah's Messenger (peace be upon him) forbade that a woman should shave her head.

Nasa'i transmitted it. 

*If someone's lice are troubling the person he can shave his head as shaving head is allowed in Islam.

Sunan of Abu-Dawood Hadith (Hadith 1955)

The Prophet (peace be upon him) saw a boy with part of his head shaved and part left unshaven. He forbade them to do that, saying: Shave it all or leave it all.

*A man is allowed to shave/trim his mustaches short but not to shave the beard by leaving it alone.

Sahih Al-Bukhari Hadith (Hadith 7.781)

Allah's Apostle said, "Cut the mustaches short and leave the beard (as it is)."

Al-Muwatta Hadith (Hadith 51.1)

Yahya related to me from Malik from Abu Bakr ibn Nafi from his father Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, ordered the moustaches to be trimmed and the beard to be left.

Sahih Muslim Hadith (Hadith 118)

The Messenger of Allah (peace be upon him) said: Trim closely the moustache, and grow beard, and thus act against the fire-worshippers. 

Abu Hurairah reported the Prophet, upon whom be peace, as saying, "Whoever has hair should honor it."

| Allah is the alone who knows best.
