Salaah

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?

Moving in ruku and jalsah

Q: In the Jalsa or Ruku in prayer, we have to stop for at least one Subhanallah, but do we have to sit in Jalsa completely motionless, or is it okay if we sit for at least one Subhanallah but in that time our arm moved a little or our leg(s) moved a little? The same question is for Ruku too, do we have to be completely motionless, or is it okay that we be in Ruku for at least one Subhanallah but during that time we move a little?
