أَوْ يَبْقَى حَيًّا حَتَّى يَمْضِيَ عَلَيْهِ وَقْتُ صَلَاةٍ وَهُوَ يَعْقِلُ، أَوْ يُنْقَلَ مِنَ الْمَعْرَكَةِ حَيًّا.
Translation: or he remains alive and conscious through the passing of a prayer time, or is taken alive from the battlefield.
The phrase while conscious qualifies the passage of prayer time; bare lapse of time without awareness is not what the clause states.
The other clause mentions being removed alive from the battlefield. Classical discussions may address surrounding circumstances, so it should not be turned into a general ethical instruction against emergency evacuation.
