let's say in 1 Rakat 2 sujud. Usually, I repeat the tasbih 3 or 5 times on each sujud. So, if in the first sujud I repeated 5 times, in the 2nd one I repeated 3 times accidentally, is it a problem? Do I have to perform Sajda Sahw for that?

I have seen some people raising hands after standing up from ruku but some don't raise their hands. Should I raise my hands or not after Ruku? What is the correct method according to Sunnah?

My Sister, My father, and I were praying and it was a silent prayer. I was silently reading Surat- Al-Fatiha and My Dad went in Ruku but I was not done reading Fatiha yet. Because he was leading the prayer I went in to Ruku also. Is this wrong and does it invalidate prayer?

I've read in a few places that in order to say either surat Al-Fil or surat Quraysh in salat both must be said in order for the salah to be valid as these surahs are very closley linked. So one would say Al Fatha, then go onto say Al-Fil then would proceed to say Quraysh (with the bismallah for each surat) before one can proceed to ruku. Is this true or is saying one or the other enough to proceed to ruku? Let me clarify, this is per rukat and not per salah. So Al-Fil is to be said, then Quraysh before ruku then on the second rukat you can choose another other sura (excluding Al-Fil and Al Quraysh)

When a brother is wearing something like t-shirt or top and hasn't tucked it into his jeans and tightened his belt or something similar part of his 'awrah such as the top of his bottom and bottom of his back get exposed in rukoo and/or sujood. Should I tell him this after the prayer (in a polite way) so that he is more careful in future and that he will need to repeat the prayer. However if I don't tell him he wouldn't know which would mean his prayer is valid or not?

I know bowing to a human being is a sin, but what counts as bowing? All types, or just ones in Islam, like ruku and sujud ?
