The source teaches:
• Tarawih is Sunnah for men and women.
• Performing it in congregation is Sunnah al-Kifayah.
• Its time begins after Isha.
• Witr may be performed before Tarawih or after it.
• Delaying Tarawih until around one-third or one-half of the night is recommended; delaying beyond half the night is not disliked according to the correct view stated here.
A communal Sunnah should not be upgraded into an invented Fard obligation.
