salaah

Performing Salaah on the 1st and 2nd floor of a musjid

Q: In few mosques there are arrangements to offer prayer with jamat on 1st and/or 2nd floor along with the ground floor. I heard from some elder person that if the distance from one row (of jamat) to the subsequent row is greater than 2 row's size than prayer of the person of the subsequent row will not be valid. Hence if the roof's height of the ground floor is higher than the 2 row's size then the prayer of the person (offering prayer) in jamat on 1st floor will not be valid. Is this case true?

Namaaz me satar ko daampna

Q:

1. Baraaye meherbaani bata dijiye ke hath se neeche kitne inch baazoo ka hisa aur gardan ka or gardan se neeche gale ka hissa or kaan ka kitna hissa nazar aaye to namaaz nahi hoti?

2. Ayk aysi chadar jis me se bohat halka sa jism nazar aye or jism ke rang ki samaj na aye ke nazar aaraha he ya nahi ya bohat halka nazar aye to kya is kapre se namaaz ho jayegi?
