Salaah

Q: Is it okay to perform wudhu whilst the azaan is being called out? Can you continue your dua during azaan or must one stop?

Q: If an imam performed Salaah in a time and he is in janaabat and he knows that he is in janaabat but still he became Imam and performed the Salaah, and he did this many times like more than 100 times and for different prayers, so now if he wants to make tauba but he still can't tell those people that repeat their Salaah because actually he also don't have any count of prayers so if he did tauba is there any possibility that Allah Ta'ala will forgive him?

Q: In salah if I make a pronounciation mistake in sajda or ruku while reciting the tasbeeh first time or second time and if I correct it in the third time, will the salaah be still valid or the moment I make a mistake in sajda or ruku the salah becomes invalid. If the mistake happens in sajda or ruku, if I correct it the total tasbeeh becomes 4 times and in other sajdas it will only be 3 times. Does this difference effect the validity of salah and how to correct myself when I make mistake in sajda.

Q: I was leading jamat at Maghrib. In the second standing, I forgot to recite aloud.  By the time someone said SubhanAllah, I was halfway in Fatiha. Upon realising the mistake, I recited Fatiha aloud from the start (repeating first half quiet and then loud). My question is, what portion of Fatiha can be repeated without sajdah-e sahwa becoming wajib?

Q: Further to your advice that arms should be fully stretched during ruku' in Salat, please advise me further. I am a tall person with long arms, therefore in ruku' my back does not become horizontal without slightly bending my elbows. Am I excused from levelling by back, or it is not a requirement at all?

Q: I just wanna ask about the sunnat-e-muakadah before fardh of zuhr. I should perform it with salaam at the end and now my question is on the third rakaat am I only going to recite fatiha and also in the forth rakaat just like praying fardh or I should recite another surah in the third rakaat and another surah in the last rakaat after faatiha?

Q: Who should lead the salaah? A hafiz of the quran who has a nice voice, but who trims his beard under the required length and who's robes flows under his ankles, or someone who isn't hafiz but is righteous adheres to the Sunnah? If the first leads the salaah should one repeat the salaah?

Q:

1. I just want to ask in the zuhr and asr salaah when you are behind the Imam are you going to recite the surah fatiha and then after fatiha do I need to recite another surah? Or only the surah fatiha?

2. Another question of mine in magrib and isha salaah on the first and second rakaat after we say ameen behind the imam, do I need to repeat the surah
fatiha silently while the imam is reciting another surah? I follow Abu Hanifa.

Q: When having multiple qadha salaah to read, what is the shortest way to read a salaah (if these are present, it's counted as done)?

Q: I just want to ask if after adhan of dhuhr there is four rakats of sunnatul muakadah right? Then the others are dividing it into two salams and on the other hand some are performing it like they are performing a salah, they pray sunnatul muakadah with only 1 salam. I follow Abu Hanifa.
