What is the ruling on offering the Dhuhr prayer with Fajr due to the lack of time between lectures and the difficulty of performing it at its prescribed time?

Muslims must adhere to the teachings of their religion, learn the rulings of Islamic law, and apply them. Performing the Dhuhr prayer before its prescribed time is impermissible by scholarly consensus, as is intentionally delaying a prayer beyond its time, for Allah Almighty says: "Indeed, the prayer has been decreed upon the believers a time-bound ordinance." It is permissible to combine Dhuhr and Asr, and Maghrib and Isha, during the time of one of them, when there are valid excuses for combining. However, in other circumstances, prayers must be observed at their prescribed times, because abandoning even one prayer until its time expires is a grave sin. Prayers performed before their time must be made up, and one must repent to Allah and strive to perform prayers at their proper times in the future. Solutions can be found, such as being slightly late for lectures or missing one to perform the prayer. If the Asr prayer time arrives before reaching home and there is a fear of missing its time, it should be prayed wherever one is. There are many solutions to maintain prayer at its prescribed time, and nothing should be prioritized over obedience to Allah.
