وَمَنْ فَاتَتْهُ صَلَوَاتٌ: رَتَّبَهَا فِي الْقَضَاءِ كَمَا وَجَبَتْ فِي الْأَصْلِ،
Translation: Whoever misses several prayers makes them up in the original order in which they became obligatory.
For instance, missed Fajr, Zuhr and Asr are made up in that order, so long as none of the exceptions to sequencing applies.
