Bells

Ibn az-Zubayr told that a woman client of theirs took az-Zubayr's daughter to Umar ibn al-Khattab wearing bells on her legs. Umar cut them off and said that he had heard the Apostle of Allah (peace_be_upon_him) say: There is a devil along with each bell [Dawud :: Book 34 : Hadith 4218]

The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Bells are the musical instruments of the Shaytaan.” [Sahih Muslim:: Book 24 : Hadith 5279]

Hence, he (sal Allahu alaihi wa sallam) said that the angels “do not accompany any people with whom there is a dog or a bell.” [Sahih Muslim:: Book 24 : Hadith 5277]

Singing and music are two of the means by which the Shaytaan corrupts people’s hearts and destroys their souls. 

Ibn Al-Qayyim said: “Among the plots and traps of the enemy of Allah, with which he seeks to ensnare those whose share of knowledge, reasoning and religious commitment is minimal and trap the ignorant and the followers of falsehood is listening to whistling and clapping of hands [Quran 8:35], and singing accompanied by forbidden musical instruments, which closes people’s hearts to the Quran and makes them devoted to immorality and sin. This is the “quran” of the Shaytaan, an impenetrable barrier which blocks them from the Most Merciful. This is the means that leads to homosexuality and fornication, by means of which the Shaytaan ensnares the hearts of those who follow falsehood and makes it appear attractive to them by way of deceit and trickery. He inspires them by means of specious arguments to regard it as something good, so they accept this idea and for the sake of singing they forsake the Quran…”
