What are the symptoms of "tying" (al-rabt) for a married man during intercourse, and what is its cure?

Whoever uses the lawful incantations (Ruqyah) will be protected by Allah from the evil of sorcerers and others. One should recite upon oneself Ayatul-Kursi, Al-Fatihah, the verses of magic, "Qul Huwa Allahu Ahad" (Surah Al-Ikhlas), and the two Mu'awwidhat (Surah Al-Falaq and Surah An-Nas). A righteous reciter can also recite these verses into water for the sick person to drink and bathe with, or blow upon them with these verses for Allah to heal them. All of this is among the means of recovery.
