Assalamualaikum, I saw a thread on twitter that said things like sharing music for example is a sin that will accumulate even after you die? Because people will still listen or share it once you're gone and you're responsible for that. Atm I follow the consensus that listening to music as long as it's not excessive or dirty is fine. But what is your thoughts on this? What hadiths are there about sins which carry on after you die? Jzk
Alaikumassalam wa rahmatullah,
The Quran says:
So let them carry their loads complete on the Day of Resurrection, and some of the loads of those they misguided without knowledge. Evil is what they carry.
The Prophet 
repeats the same message in this hadith:
He who called (people) to righteousness, there would be reward (assured) for him like the rewards of those who adhered to it, without their rewards being diminished in any respect. And he who called (people) to error, he shall have to carry (the burden) of its sin, like those who committed it, without their sins being diminished in any respect. (Sahih Muslim 2674)
As far as I can find there are no explicit hadiths that deal with the issue of sins that continue to harm a person after death. But from the above, and from narrations that talk about good deeds that continue to benefit a person’s record after death, scholars conclude that bad deeds that continue to exert their efforts after one’s death will continue to harm that person’s record too.
Music is merely a set of ordered sounds, similar to speech (and similar to the songs of birds). And similar to speech, it is neither good nor bad by itself. It is only once we examine its purposes, effects and uses that we can decide whether it is a good thing or bad thing. Sharing music on social media is therefore similar to sharing anything else, such as a speech, picture or quotation.
Music that is beautiful (such as some classical Western or Middle Eastern music) carries a positive value according to Islamic aesthetics, meaning that it is not just morally neutral, it is morally good and beneficial. (See my essay Beauty as Pointer: An Islamic Theory of Aesthetics). There is also music that is neutral or negative in its value. Most pop music combines both music and poetry of negative value to create a message that positively goes against a pious and God-fearing state of mind.
There are also types of music that serve a utilitarian purpose, such as upbeat music for exercising. There is nothing wrong with that.
