Salaah

Q:

1. I prayed Fajr at about 6:02 and it expires on the calendar at about 6:06, but before I prayed I looked outside and at first I noticed it was light and at the distance I seen in the clouds a reddish smudge, like at the time of Maghrib. Can Fajr expire before the calendar time or is it 100% accurate?

2. I prayed Fajr Qada in-case and at my last rak'ah in tashahhud I didn't have khushoo as I needed to relieve myself, does this affect the validity of my prayer? I leant on one side to hold it and before tasleem I moved back.

Q: While reading salah saying Allahu akba will that break my salaah? Suppose I'm going to ruku if I say Allahu akba and to correct it can I again say allahu Akbar when I'm in ruku or doing this will break my salaah?

Q: Asr jamaat in the Tableelighi jamaat Musjid is at 4:45 PM whereas in the Ahle Hadith Musjid it is 3:45 PM. So can I offer my asr Salaah at the Ahle Hadith Musjid?

Q: If one misses the sunnat salaah of fajr, then should he join the Imaam in jamaat and leave out the sunnats?

Q: I want to know what are the faraaidh of Salaah?

Q: I know that if you miss a waajib in prayer, you must perform sajdah-e-sahw, and if you fail to do so, you should repeat the prayer, so long as its time remains. However, once the time for the prayer is over, the prayer is not to be repeated. What is the status of missing a waajib act in a qada prayer? If you miss a waajib in a qada prayer, and you failed to perform sajdah-e-sahw (or you performed sajdah-e-sahw incorrectly, i.e. you made only one sajdah), do you then have to repeat that qada prayer? Is it merely recommended to repeat that qada prayer or is it waajib to repeat that qada prayer?

Q: In Jalsa, I mistakenly recited approximately half of the duaa in Janaazah salaah for an adult. I was a munfarid.

(1) I made Sajda Sahw. Is this sufficient?

(2) Must I repeat the Salaah?

Q: In ruku should the arms be kept straight or should they be bent with the elbows sticking out?

Q: A person is performing Salaah reading his dhor and he forgets where he is. He thinks for a few seconds and goes back and continues. Does this pause make sajdah sahw necessary?

Would this change depending on the Salaah he was performing e.g. if it were sunnats or taraweeh or fardh etc?
