Today, I was wondering if swallowing dead sperm a Zina or a graveful sin. What is the punishment for it if it is both or just one of them?
As salaamu alaikum,
Swallowing sperm would be impermissible due to its being filth. However, there is no punishment for swallowing it. Pray to Allah for forgiveness and avoid repeating it.
In reference to touching areas where sperm has been and consequently dried then there is no transfer of filth and no harm to those who may have touched those areas. The issue or concern would be with the area of prayer and the clothes or accessories one prays with.
If, for instance, there was sperm on the rug but a prayer mat was placed over it. There would be no problem with praying in that area. However, if there was, for instance, sperm that was on a cell phone and you prayed with the cell phone in your pocket it would be best to make up the prayer if you remembered within the prayer time. Otherwise, if the prayer time exited the prayer would be sound, Insha'a Allah.
and Allah knows best.
