أحسن الله إليكم شيخنا In the university there's a single prayer room for both male & female, separated by drapes and separate doors for entry/exit. If a brother when praying alone and hears that a sister entering from the door behind, should be break his salah and leave? بارك الله فيكم وحفظكم

Ustadh AbdulAziz al-Haqqan

No, because they are separated.
