إِلَّا أَنْ يَخَافَ فَوْتَ صَلَاةِ الْوَقْتِ، فَيُقَدِّمَ صَلَاةَ الْوَقْتِ عَلَى الْفَائِتَةِ، ثُمَّ يَقْضِيهَا.
Translation: But if there is fear that the time of the current prayer will expire, the current prayer is offered first, then the missed prayer is made up.
This is the first exception to sequencing: narrowness of the current prayer time. The missed prayer remains due; only the order changes.
