Answer:
(Fatwa: 471/429=B/1430)
The interior part, veranda and courtyard of mosque was built for the purpose of prayer and the salah was also continuously performed there by forty years, then all these portions are included in mosque and are respectable just like mosque. It is neither lawful to erect toilet there nor wudhu khanah. The veranda shall remain mosque forever and only salah can be offered there, it cannot be converted into anything else.
