Is it permissible to break the fast and pray Maghrib in the institute, or must it be delayed until reaching home, knowing that the time of arrival at home will be about half an hour after the Maghrib call to prayer, and in the event of praying in the institute, the transportation will be missed and one will be delayed in reaching home?

Initiating prayer at the beginning of its prescribed time is among the best deeds in the sight of Allah, except for the Isha' (night) prayer and the Dhuhr (noon) prayer during intense heat. Similarly, it is recommended to hasten breaking the fast. However, if this is difficult for you, there is no harm in delaying the prayer to perform it at home, provided that you are reasonably certain of arriving before the Isha' call to prayer, and you can break your fast with some dates on your way.
