مَتَى الْاِجْتِمَاعُ؟ بَعْدَ الظُّهْرِ.
When is the meeting? After noon prayer.
يَبْدَأُ الْاِجْتِمَاعُ بَعْدَ الظُّهْرِ فِي الْقَاعَةِ الْكُبْرَى.
The meeting begins after noon prayer in the large hall.
The first exchange asks for the time only; the short reply fully meets that request. The second adds location, which can be beneficial when an attendee needs to plan where to go. Neither brevity nor length alone establishes eloquence.
The communication goal, the information needed and the listener's prior knowledge determine whether concise expression, an adequate middle course, or useful amplification best fits the circumstances.
