Salaah

Gap of 3 saffs between two saffs

Q: If in congregational prayers and Jumu'ah and Eidain, the Imam is in the indoor hall of the masjid and saffs are made behind him and the door of the hall is closed but not locked and saffs are also made outside, but there is a distance of 3 saffs between the last indoor saff and the first outdoor saff, are the congregational prayers or Jumu'ah or Eidain prayers valid?

Salaah becoming qadha due to not making fardh ghusl after becoming baaligh

Q: If a male becomes baaligh by having wet dream and ghusl becomes fardh on him, but he doesn't know that in Shariat you have to perform ghusl after having a wet dream. So he keeps praying with just making wudhu and after 3-4 months of his puberty, he comes to know that ghusl becomes fardh by wet dream. So are all his prayers in these 3-4 months counted or does he have to make qadha?

While offering these prayers again will he make intention of praying qadha prayer or will he make intention of repeating the prayer (I'adah)?

Sahib-e-Tarteeb making qadha of Zuhr Salaah after performing Asr Salaah

Q: I have a question about the Mas'ala of Sahib-e-Tarteeb:

1. If a person is Sahib-e-Tarteeb and he misses a prayer, for e.g. Zuhr. And then prays Asr and after praying Asr, he prays the Qaza of Zuhr. So obviously his Asr prayer is invalid. But what if after praying his Zuhr Qaza, he misses 6 more prayers. So he no longer remains Sahib-e-Tarteeb. So by missing 6 prayers will that Asr prayer which he offered becomes valid?

2. What if he then again offers all those 6 prayers' Qaza and again becomes Shahib-e-Tarteeb, will now his Asr prayer become invalid again?
