Q: Allah Ta'ala affords and blesses me with Tahajjud. Some times a few minutes before Fajr, I am sometimes so rushed to perform this ibaadah that I tend to forget the proper way, mindset and recommended acts whilst performing this Salaah.

Q: A family moves into an apartment, they use a well known Qibla finding app to locate the Qibla direction and pray. Months later a neighbour points out that the direction is wrong and they must face the other direction. The difference is about 90 degrees apart. What happens to those Salaah that were prayed in the incorrect direction, are they valid or do they need to be repeated? 

Q: When reading in jamaat for zohr, in the second rakaat in tashahud, I accidently start reading the durood thereafter the imaam stands up to read the third rakaat. Am I required to read sajda sahw when the Imam concludes the prayer?

Q: If one hears multiple azaans from different masaajid, does one have to reply separately to each azaan and recite the dua after azaan separately for each azaan? Kindly explain the ruling when one is in the musjid and when one is out of the musjid.
