وَالتَّكْبِيرُ عَقِبَ الصَّلَوَاتِ الْمَفْرُوضَاتِ.
Translation: The takbir is recited after obligatory prayers.
The phrase “after obligatory prayers” distinguishes the takbir from the prayer’s internal takbirs. The jurists also discuss whether its obligation applies only in particular congregational and residence situations or more generally.
