al-Qasim ibn Muhmmad* was asked about music and said the following:
“On the day of Judgement, when Allah distinguishes between truth and falsehood, where will music be?”
The questioner: “It will be in the precincts of falsehood!”
al-Qasim: “Then, ask yourself.”
Quoted by Imam al-Muhasibi in Risalah al-Mustarshidin
* Al-Qasim bin Muhammad was the grandson of Abi Bakar al-Siddiq [May Allah be pleased with them all], one of the seven great jurist of Medina and considered one of the great students of the Companions [May Allah be pleased with them]. He was born 37 A.H and died 106 A.H.
