Salaah

Q: What are the words for the iqamah? I have heard some people say that everything must be repeated twice and some say that most of the words are repeated once and only the ending is repeated twice.

Q: A person read in his Awwabeen Salaah a portion of his qiraat alound and a portion softly. Is his Salaah valid? If valid, is sajda-e-sahw waajib upon him?

Q: In maghrib I missed 2 rakaats and joined the 3rd rakat, how should I complete the two rakaats?

Q: Do we have to make Qadha of Sunnah also when we make Qadha of Fardh in each of the Salaah we have missed. What is the Shariah Ruling on this?

Q: I started praying Maghrib Fardh about 30-31 mins after Maghrib started (according to the calendar) and finished 41 mins or so after Maghrib started. I am not sure if I performed it on time as it was already dark outside. Do I make up the prayer or is it valid because my intention was to pray the fardh of maghrib? I also prayed 2 sunnah what about them?

Q: I would like to know if it is permissible to read Salaah with make-up on?

Q: I have been missing and delaying prayers due to the time it takes me to make istinja and Wudu because I am suffering from OCD/Waswasas. I feel like a kafr because I have heard that your're a kafr if you miss prayers without an acceptable reason. I am definitely not missing/delaying prayers on purpose so am I considered a kafr? What should I do about this situation?

Q: Can you break your salah if someone is knocking on your front door or ringing your phone?

Q: What should be done if while praying one is not sure if they broke their wudhu due to wind? I often try to hold the wind but I am not sure if
I was able to hold it or if I let it out slowly?

Q: How long does the Aa in Aameen have to be stretched for?
