Method of Salaah

Sunnah method of Salaah

Q: When you perform salaah, when doing takbeer to start, should we look up or down? And after raising from rukuand saying "samirallahhulimanhamida", some says you have to say "allahumma rabbanawakalhamd" and others only "rabbana lakalhamd"? Which one is correct according to sunnah? And is it obligatory to say it? If i did not say it, are all my prayers invalid?

Incorrect recitation

Q: I realized that I was reading surah Ikhlas pausing in letter Mim (everywhere where it has sukun in this surah) in last ayats making it as double letter – shadda. Does it change the meaning? If during salah I realize I did it again, do I have to start salahs from the beginning or I have to make sajda-sawh or can proceed without it as normal? Could you please also let me know, is it true that kaza of sunna of fajr cant be made in a fajr time, but has to be made any other time after fajr?

Trying to pronounce the letters correctly

Q: I would like in shaa Allah to ask about things I face during my salah as every time I wonder if they break my salah or not. Allah created me in a way that it is a bit difficult for me to say letter R. In normal life its not obvious, no one even notices it, even me, but when it comes to say rrrrrrrrrr then I cant do that, which means Bismillehirrahmanirrahim is a bit difficult for me to say, I loose the sound of R if I am in my relaxed state. I have to give real efforts in order to pronounce it. My efforts don’t help much, R is still not so clear and I feel I only lose concentration in salah. Do I have to be making efforts or can be relaxed, how important is to pronounce R clearly? It’s the way Allah created me, can I be relaxed in my salah in shaa Allah? Other things that I experience during salah: last H in bismillehirrahmanirrrahim doesn’t come as soft as needed from my throat, because I loos air already saying all other letters in this words, so if it comes a bit harder then must be, if its close to the other Ha, is it something that voids my salah or requires sajda-sawh? In siratalmustaqim, letter Ta is difficult for me to say real hard, as to say R takes me to open my mouth and then its inconvenient for me to pronounce Ta hard as it must be. I should try to pronounce it correct but would like to know if mistake in this letter breaks salah? If saying D in gayrilmehDubi softer then it must be break salah? As above, in bismillehirrahmanirrahim, I cant stay long in double R, so I feel that I say double R, but sometimes feel I was to fast, is it ok or voiding salah? I noticed, when I try to say second double R properly, and then I have no air enough to say H in Rrahim soft as needed. In subhanerabbiyelA’le its hard for me to make a pausa in Ain as I was taught. Is any of these mistakes above break salah, require to read it again or require sajda-sawh, could you please let me know?
