Is soft tune music in video advertisments of selling products allowed? Music which has no obscene langauge, or nudity, no violence or sexual behaviour, Rather just soft tone played by instruments to act as background music in the advertisment of a product
Music is prohibited. So It will not be permissible.
(31:6) وَمِنَ النَّاسِ مَن يَشْتَرِي لَهْوَ الْحَدِيثِ لِيُضِلَّ عَن سَبِيلِ اللَّهِ بِغَيْرِ عِلْمٍ وَيَتَّخِذَهَا هُزُوًا ۚ أُولَٰئِكَ لَهُمْ عَذَابٌ مُّهِينٌ
And of the people is he who buys the amusement of speech to mislead [others] from the way of Allah without knowledge and who takes it in ridicule. Those will have a humiliating punishment.
