wa'alaikuma s'salaam,
There are those who say it's allowed and some of them go fatwa hunting to support their desires. But Major and majority scholars agree on music being haram and a tool of the shaytan.
Shaytan says:
"Surely I will sit in wait against them on Your Straight Path. Then I will come to them from before them and behind them, from their right and from their left, and You will not find most of them as being grateful ones (i.e., they will not be dutiful to You)." [Soorah al-A'raaf 7:16-17]
In an hadith, shaytan also says "I will use musical instruments as my tools to stir the hearts and lead the sons of Adam astray."
Allah says:
"But there are, among men, those who purchase idle tales, without knowledge (or meaning), to mislead (men) from the Path of Allaah and throw ridicule (on the Path): for such there will be a humiliating Penalty. When Our Signs are rehearsed to such a one, he turns away in arrogance, as if he heard them not, as if there were deafness in both his ears: announce to him a grievous Penalty." ( Luqmaan: 6-7).
Ibn Mas`ood said: "I swear by Allaah that these "idle tales" are nothing but songs." He repeated it thrice. Ibn `Umar and Ibn `Abbaas, may Allaah be pleased with them, said the very same thing. These Companions were living when the Qur'aan was revealed and hence they are among the most versed in interpreting the words of Allaah. They interpreted these "idle tales" as songs.
The Messenger of Allaah (peace and blessings of Allaah be upon him) said:
“Among my ummah there will certainly be people who permit zinaa, silk, alcohol and musical instruments…” (Narrated by al-Bukhaari ta’leeqan, no. 5590; narrated as mawsool by al-Tabaraani and al-Bayhaqi. See al-Silsilah al-Saheehah by al-Albaani, 91).
This hadeeth indicates in two ways that musical instruments and enjoyment of listening to music are haraam. The first is the fact that the Prophet (peace and blessings of Allaah be upon him) said: “[they] permit” which clearly indicates that the things mentioned, including musical instruments, are haraam according to sharee’ah, but those people will permit them. The second is the fact that musical instruments are mentioned alongside things which are definitely known to be haraam, i.e., zinaa and alcohol: if they (musical instruments) were not haraam, why would they be mentioned alongside these things? (adapted from al-Silsilah al-Saheehah by al-Albaani, 1/140-141)
Messenger of Allah (Allah bless him & give him peace) said: “Song makes hypocrisy grow in the heart as water does herbage” (Sunan al-Bayhaqi).
An appropriate exception
The exception to the above is the daff – without any rings (i.e., a hand-drum which looks like a tambourine, but without any rattles) – when used by women on Eids and at weddings. This is indicated by saheeh reports. Shaykh al-Islam (may Allaah have mercy on him) said: But the Prophet (peace and blessings of Allaah be upon him) made allowances for certain types of musical instruments at weddings and the like, and he made allowances for women to play the daff at weddings and on other joyful occasions. But the men at his time did not play the daff or clap with their hands. It was narrated in al-Saheeh that he said: “Clapping is for women and tasbeeh (saying Subhaan Allaah) is for men.” And he cursed women who imitate men and men who imitate women. Because singing and playing the daff are things that women do, the Salaf used to call any man who did that a mukhannath (effeminate man), and they used to call male singers effeminate – and how many of them there are nowadays! It is well known that the Salaf said this.
