Mistakes in Qiraat

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?

Stopping one's recitation during the course of the discussion

Q: Respected Mufti, I stood behind in prayers where these verses were recited and on the second verse the Imaam would stop the surah and go into ruku. Is this allowed? If not, is this in violation on any of the etiquette of recitation of the Quran?

فَحَشَرَ فَنَادَىٰ [٧٩:٢٣]

فَقَالَ أَنَا رَبُّكُمُ الْأَعْلَىٰ [٧٩:٢٤]

Omitting a Surah in-between two Surahs

Q: I have been told that if, for example one reads surah Nasr in the first rakaat, then in the next rakaat one cannot read surah Ikhlaas. One must recite the surah immediately thereafter or there should be at least a gap of two surahs. Please clarify this rule for me (e.g., does it apply only to short surahs? Does it apply to a 4 rakaat salaah as well?)

Doubts in Surah Faatiha

Q: In my 'Asr Salaah I recited a verse of Surah Faatihah and whilst reciting I thought I made a mistake, and thought I'd repeat that verse and I didn't
stop reciting until I finished the verse, and then I recited again, but during the verse in which I thought I made a mistake, I was like “Shouldn't I stop?" But I carried on until finishing that verse; now I wonder, does this count as a purpose addition in prayer by finishing the verse in which I thought to have made a mistake? And is my Salaah valid?

Performing one rakaat

Q: First rakat of ishaa I said 'Ar-Rahman Ar-Raheem' but then I don't know whether I said the ha or HA with 'Ar-Raheeem'. I chose to ignore it as a doubt. During Salah I made many mistakes and corrections in the essential aspects - then after completing the prayer [all four rakaats] I ended prayer and did two sujood uh sahw. I went downstairs to get a drink, came back up then I still had the niggling doubt about whether I said ha or HA in 'Ar-Raheem' so I thought like you know it hasn't been a long time since I made Salaam so I said takbir and performed 1 rakaat in replacement of the rakaat in which I doubted with the full tashahhud and exited prayer and did two prostrations of forgetfulness Now plz tell me is my prayer valid or not?
