salam walekum agar hum train m h aur wajib namaz ada krna h to kya hum distenation se kibla rukh pata kar k namaz baith kr pad kaste h aur agar train chal g to kya meri namaz sahi mani jaye g kyu k train chalne k bad to kibla rukh change ho jaye g

W alikum Salam
Agr time hai aur train rukegi to sabr karen jub kisi station par ruke to wahan utar kar parye.
Agr waqt ja raha hai aur koi rasta nahi hai to jitna mumkin ho qibla rukh parye.
