Taraweeh

Mistakes in taraweeh salaah

Q: With regards to Taraaweeh:

1. An Aayah was recited correctly. The Imaam thereafter repeated the Aayah and changed it (incorrectly) due to some doubt. Is the initial correct recitation or the second recitation which was incorrect taken into consideration? Does the Aayah have to be repeated?

2. For the purpose of listening to the Luqmah of a Saami', the Imaam remained silent for the duration of 3 Subhaanallaah or more (he did not recite Qiraat for that duration). Should Sajdat-us-Sahw be made?

3. Additionally, if a person because of some disturbance missed an Aayah in Surah Faatihah, or one sentence in his At-Tahiyyat, does he have to make Sajdatut-us-Sahw? To what extent is the Surah Faatihah and At-Tahiyyat Waajib?
