People who Perform the Isha Salaah in the Masjid and then perform the Taraaweeh salaah at Home

Q: Salaah-199: Will a person be sinful if he performs the Isha salaah with Jamaa'ah in the Masjid and then performs the Taraaweeh salaah alone at home?

Answer: Performing the Taraaweeh salaah in the Masjid with Jamaa'ah is Sunnah Mu'akkadah alal Kifaayah, meaning that if there are people performing it in the Masjid in congregation, the person performing it alone at home will not be sinful. He will of course be deprived of the virtue of performing salaah with Jamaa'ah.
