surah faatiha

Q: If due to some disturbance, a person missed an Aayah in Surah ​Faatihah, does he have to make Sajdah-e-Sahw? 

Q: While offering zuhr prayer alone, I mistakenly started to recite surah al faatihah in the rukoo. Should I have offered Sejdah sahw?

Q: A man joined the Salaah after the Imaam completed the Surah Faatihah. Should he recite sana? 

Q: How long should one remain silent between fatihah and the next surah in jummah prayers? The Imams of the Haram usually remain silent after aamen for half a minute.

Q: Is it compulsory to recite Surah Fatihah in the third and fourth rakat of farz salaat. I have read somewhere that its not compulsory when reading salaat individually without jamaat.

Q: I read in tafseer Ibn kathir that Surah Fateha has seven verses in it and there are some Hadith also there in that tafseer from two sahihs that Bismillahir rahman nir Raheem is a first verse of Surah Fateha. There are only seven verses in Surah Fateha. Now, I saw in Sahih Bukhari Narrated From Anas bin Malik (radhiyallahu anhu): Nabi (sallallahu alaihi wasallam), Abu Bakr (radhiyallahu anhu) and 'Umar (radhiyallahu anhu) used to start the prayer with "Alhamdulillahi rabbil aala min" Vol-1,book 12, number 710. ( Sahih Bukhari-- characteristics of prayer). Now, what should we start the prayer with?

Q: I read in tafseer Ibn kathir that, Salah will be a invalid if Surah Fateha is not recited in it. Is it permissible to recite Surah Fateha in Salaatul Janazah?

Q: I missed reciting the qiraat after Surah Faatihah in one rakaat of my esha salaah and I performed sajdah-e-sahw. Is sajdah-e-sahw sufficient or do I have to repeat the salaah?
