From Wikipedia:
Qasidat-ul-Burda (“Poem of the Mantle”), as it came to be called, is an ode composed by the eminent Sufi Shaikh Sharafuddin Muhammad Al-Busiri (d. 1296) of Egypt. The poem, whose actual title is al-Kawakib ad-Durriya fi Madhi Khair-ul-Bariya (“Celestial Lights in Praise of the Best of Creation”), is recited throughout the Muslim world.
al-Busiri composed the Burda while suffering paralysis of half his body. After praying to God for health, he fell asleep and dreamt of reciting his compilation to Muhammad. The prophet touched the paralyzed body parts and threw his mantle (burda) over al-Busiri. On arising, the shaikh was cured. His story spread and the poem became famous.
Muslims venerate the ode. The poem is memorized and recited in congregations, and its verses decorate the walls of public buildings and mosques. Some Muslims believe that, if recited with love and devotion, the Burda can cure diseases and purify hearts. Over 90 commentaries have been written on this poem and it has been translated into Persian, Urdu, Turkish, Berber, Punjabi, English, French, German, and other languages.
The Burda is divided into 10 chapters and 160 verses. Each verse ends with the Arabic letter m?m, a style called m?m?ya. The 10 chapters of the Burda comprise
* On Lyrical Love Yearning
* On Warnings about the Caprices of the Self
* On the Praise of the Prophet
* On his Birth
* On his Miracles
* On the Exalted Stature and Miraculous Merits of the Qur’?n
* On the Ascension of the Prophet
* On the Chivalrous Struggle of God�s Messenger
* On Seeking Intercession through the Prophet
* On Intimate Discourse and the Petition of One�s State

isn’t a woman’s voice considered awrah?
BismillahirRahmanirRaheem
as-salamu’alaikum,
No the woman’s voice is not considered Awrah (see: http://qa.sunnipath.com/issue_view.asp?HD=3&ID=4835&CATE=368)
But there is a matter of what is best and proper according to the circumstance, and judgement. If there is fear of fitnah in your listening to this Qasidat al Burdah, in that you have become sexually excited, then yes indeed it becomes awrah for you and its best you don’t hit the play button. Though, there are probably quite a few things that you would need to avoid in life as well.
Interesting that you would reference SunniPath because of the following fatwa:
http://qa.sunnipath.com/issue_view.asp?HD=1&ID=1786&CATE=142
“Any singing that is accompanied by other sins, such as songs that consist of unlawful, immoral, and sexual themes, or it is sang by non-Mahram women, etc will also be unlawful. This ruling is also with the consensus of all the scholars.”
wa salam alaikum!
as-salamu’alaikum,
SunniPath is a very diverse site and on that subject there are numerous opinons on different subjects. On the subject of the voice of a woman being Awrah, the answer seems to be unanimous.
wa `alaikum salam,
Despite their agreement that the female voice is not `awra, several of the answers indicate that listening to a female singing, regardless of the level of excitement incurred, is disliked or forbidden.
For example, Shaikh Amjad, whose fatwa you linked to, says, “As for singing, scholars stated that hearing the singing of a woman is offensive, unless it fitna is feared from it, in which case it becomes unlawful.” And Shaikh Faraz concurs, “It is not permitted for men to listen to the singing or recitation of strange (non-mahram) women, whether it is with or without the fear of fitna.” I can’t find a fatwa that diverges from this opinion on the site, w’Allahu a`lam. Perhaps its an issue that the scholars disagreed about; I don’t know.
Jazak Allahu khairan.
