What is the type and effect of the sorcery that involves finding blood-stained underwear in the toilet siphon, and what does it do?

Sorcery is one of the gravest sins, and it is disbelief (kufr). The punishment for a sorcerer is death. It employs wicked methods, including the use of impurities and menstrual blood.

To counteract this sorcery, you must: 1. Extract the magical materials and destroy them by tearing and burning them. 2. Fortify the household members with remembrances (adhkar) and lawful incantations (ruqyah (definition) shari'ah), and maintain the morning and evening remembrances, as well as those for sleeping and waking. 3. Persistently recite the Quran, especially Surah (definition) Al-Baqarah and the Mu'awwidhat (Surahs Al-Falaq and An-Nas). 4. Have a good opinion of Allah and be certain that no one can harm another except by His permission. 5. Avoid stirring up doubts and ill-will towards people, as the matter is nothing more than a plot from Satan.

Destroying these items will invalidate the sorcery, Allah willing, while also being careful not to let your personal belongings fall into the hands of untrustworthy individuals.
